Hi there,

I'm trying to figure out why this function is only working for the first face:
https://github.com/dfelinto/blender-git/blob/bake-cycles/source/blender/render/intern/source/bake_new.c#L104
I'm getting bad data when trying to read the MTFace for any face that
is not the first one:
((MTFace *)cdl[0])-uv
{0.50238, 1}, {0, 0}, {1, 0}, {0, 0}}

6.9779858e+22, 4.66808809e+24}}
As you can see the 2nd face is bad (2 verts are at 0, 0) and the 3rd
one is totally bogus. The mesh itself is very simple, if you want to
check out (it's the one in 3-Tris):

While at there another question:
Is there any way to get the number of verts of a MTFace?

Re: [Bf-committers] help with tessface, CustomData and MTFace
Built your patch and realised that cdl isn't MTFace**, which is what the fix I suggested is for. This is what you actually need: MTFace *mtface = ((MTFace *) cdl)[i]; The original code was creating a ref to CustomDataLayer*, indexing into it, and only casting to MTFace* as the last step. The structs are different sizes so things ended up out of alignment.

The most recent SMD/DMX tools by Varsity (of facepunch) are by far the best, and are really easy to use.

The .smd/dmx files and the .qc could be uploaded together and compiled remotely (and locally for testing). This would maximize useability for new modelers I think. Another major feature that would be very useful for modders is the ability to create source materials for their models directly within blender. At the moment there is no VTF support, so we use tga or png and convert them externally. Blender already has a good material system but being able to generate a .vmt from your material settings would be great as well. At least the basics like phong/cubemap and normals. These two features would immediately allow people who already model with blender to make models straight away. Hell I have a whole list of stuff but I digress.

We would like to make our digital distribution platform Steam (www.steampowered.comhttp://www.steampowered.com) one of the places where you can download Blender. The long-term goal would be to make it easier for people to build their own mods for PC games with Blender and share these mods with other gamers. So I was wondering if there are any Blender users on this list who are interested in PC games and could see themselves working on an integration between Blender and PC games that offer official modding support such as DOTA 2. Long story: Valve is a company that is built on modding. The original Half-Life was built on a modified version of the Quake engine. All our major games since then started out as mods which we found cool, hired the people who built them and released them as major game titles. This is true for Counter-Strike, the original Team Fortress, Day of Defeat and DOTA 2 (Portal was not technically a mod but a student project - but you see the pattern). Similarly, one of the most successful features of our Steam platform is the Steam Workshop (http://steamcommunity.com/workshop/), which is an interface for users to share, discover and install mods for their games. Essentially, you can publish your mod there and other gamers can bring your mod into their games with a single mouse click. This is something that we think would be a cool feature for Blender to tap into. Like modeling a sword in Blender, pushing a button and having it available to all users of Skyrim. But we bet there are more creative ideas out there than this one. What we are currently looking at is offering a completely vanilla version of Blender as a free download on Steam that is completely the same as that offered on other websites. We'd hope that this will get enough of our users exposed to and interested in Blender so they will be inclined to work on Blender plugins that would talk to Steam's backend services such as Workshop.

This looks like something that would concern the reference counting system of a memory manager/garbage collector rather than users. This would not have been a problem if we had an explicit way to delete data and data always stayed in blender even after closing the program. A user will usually want his data to stay if he creates it and go if he deletes it. Currently there are two problems with the approach we have: 1) You have to close the program to delete all unreferenced data and 2) You can't create a library of datablocks without explicitly setting a fake user, which is not the best of options.

[Bf-committers] ListBase vs. slots
I'm trying to refactor some code from the array of pointers solution
used by material/texture slots to ListBase, as a result of code review.
But I'm beginning to think that Blender doesn't support that.
The code in question is my Action Library patch from last October. It
allows AnimData to store a list of associated Actions in addition to the
single active action it currently stores.
http://projects.blender.org/tracker/index.php?func=detailaid=28453group_id=9atid=127
ListBase usually takes IDs directly, but since I'm not creating a global
list of IDs I am having to use LinkData instead. For reference:
typedef struct LinkData
{
struct LinkData *next, *prev;
void *data;
} LinkData;
This works fine in C, but accessing items with Python crashes. Python
can walk the list just fine (*next and *prev are as it expects) but
doesn't seem to understand the *data indirection of LinkData.
Is there a RNA setting I've overlooked here? If not, I vote for
supporting ListBase-LinkData collections. They are immediately
applicable to material slots, texture slots, and I suspect particle
system settings too. :)

((LinkData*)rna_iterator_listbase_get(iter))-data);

The code in question is my Action Library patch from last October. It
allows AnimData to store a list of associated Actions in addition to the
single active action it currently stores.
http://projects.blender.org/tracker/index.php?func=detailaid=28453group_id=9atid=127
ListBase usually takes IDs directly, but since I'm not creating a global
list of IDs I am having to use LinkData instead. For reference:
typedef struct LinkData
{
struct LinkData *next, *prev;
void *data;
} LinkData;
This works fine in C, but accessing items with Python crashes. Python
can walk the list just fine (*next and *prev are as it expects) but
doesn't seem to understand the *data indirection of LinkData.
Is there a RNA setting I've overlooked here? If not, I vote for
supporting ListBase-LinkData collections. They are immediately
applicable to material slots, texture slots, and I suspect particle
system settings too. :)

[Bf-committers] Makesdna fails with wrong pointer syntax
Hi everyone. I just spent 1hr+ hunting an annoying bug down. The following declaration in a DNA header will cause makesdna to fail with a generic strut unknown error, despite being entirely legal: ID* data; Putting the space in front of the asterisk avoids the problem. Fix please? :) ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
Re: [Bf-committers] Fully qualified names for channels in actions?
You can add a constraint that forces one object to move with the other. On 19/09/2011 6:06, Tobias Oelgarte wrote: I just stumbled upon a simple task. I have two objects (a sphere and a cube for example) and i wanted to control their locations with _one_ action. That simply isn't possible with one action alone, since both objects will share the location-channel (sitting on top of each other). Is there a way to store the location of two objects in one action or will i have to combine both actions with the NLA or the need to parent both to the bones of an armature? If it isn't possible, wouldn't it not make sense to (optionally) use something like fully qualified names in a way, that both locations could be stored inside the same action? I may be wrong, but i would find it useful for this properties.

Re: [Bf-committers] Two new patches
I made the patch because PFM is the only format from which HDR skyboxes and cubemaps http://developer.valvesoftware.com/wiki/HDR_Skybox_Creation can be created for the Source game engine. I imagine that there are plenty of other obscure/proprietary texture tools that require it too, but I couldn't name any. With the format being so simple it wouldn't surprise me to see people starting to include it in their own pipelines once it's a part of Blender. On 31/08/2011 6:00, Campbell Barton wrote: Having support for a very simple floating point image format seems reasonable - EXR/TIFF/DPX/JPEG2000/HDR are a bit complicated requiring libs to properly support and some of these do conversions from float to fixed 16-32 bits per channel, gamma blah blah or use lossy compression. So I see there is something nice about being able to write a float image to disk without trying to be *smart* about it like DPX/KPEG2000 do. The patch is very small and other apps support it so should be ok? ...I'd like to know anyone uses this image format though, or if there are areas where its in common use.

[Bf-committers] Environment map render op
A while ago I added a skip cameras option to the render operator (in my local copy), to improve the export of environment maps. This works well, but looking ahead to possible trunk integration I'm not sure that it is good API design: external renderers will need to be updated to account for both the new setting and, more importantly, the fact that a render can now go ahead without an active camera. What is the best approach to making these changes play nicely? Do external renderers expect these kind of breaking changes on new Blender versions? ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
Re: [Bf-committers] Syntax Highlighting Alternate Languages
There's no reason to keep the keywords list as a Python var. Who needs constant access to it? It can be converted to a native C vector/array/whatever immediately. Any highlighting extension that isn't scriptable isn't worth doing IMO. On 27/07/2011 9:25, Benjamin Tolputt wrote: I'm pretty sure that putting the parsing code into the Python layer would slow the syntax highlighting code quite dramatically and, as such, is not likely to get the core team approval (let alone be appreciated by the users). I like the idea of that kind of flexibility, but the code is currently quite low level speedy (integer comparisons from a char array). The speed hit to jump up to Python (with the string passing, Python string comparisons, and return path) is most likely going to rule this out almost completely. That said, in terms of the priority request, I'm willing to do the low-level code stuff myself. This isn't a request for other developers to code something for me, it is a request to pre-check whether it is worth putting the code together myself. It is contained in perhaps two files, there are no changes to the API required, and it is very close to a copy/paste job with alternate means of detecting comments, strings, and special strings. The changes are small, there is no performance penalty, and the upside is (for people like myself) quite high. If I cannot get approval for this - I don't think integrating Python would be worth mentioning ;) ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

Instead in python31.dll there's an entry for PyModule_Create2 and none for PyModule_Create2TraceRefs. bash-3.1$ cd lib/windows/python/lib/ bash-3.1$ grep -nr PyModule_Create2[^T] * Binary file python31.dll matches Binary file python31.lib matches Binary file python31mw.lib matches Binary file python31mw_d.lib matches bash-3.1$ grep -nr PyModule_Create2TraceRefs * python31_d.def:122:PyModule_Create2TraceRefs Binary file python31_d.dll matches Binary file python31_d.lib matches Binary file python31_d.pdb matches Binary file python31mw.lib matches Binary file python31mw_d.lib matches Turns out that the python headers are replacing symbol definitions depending whether you are building a python release or debug dll. modsupport.h:94: #ifdef Py_TRACE_REFS /* When we are tracing reference counts, rename PyModule_Create2 so modules compiled with incompatible settings will generate a link-time error. */ #define PyModule_Create2 PyModule_Create2TraceRefs #endif object.h:54: /* Py_DEBUG implies Py_TRACE_REFS. */ #if defined(Py_DEBUG) !defined(Py_TRACE_REFS) #define Py_TRACE_REFS #endif pyconfig.h:369: #ifdef _DEBUG # define Py_DEBUG #endif The default user-config doesn't set _DEBUG so Blender compiles against PyModule_Create2 which doesn't exists in python31_d.dll, hence the crash.

Python 3.1 debug dll is built dynamically linking against msvc9 debug runtime, so if you want to run debug with other than vs2008, you'll have to acquire the appropriate debug runtime dlls. These are not redistributable, so you'll need to get vs2008 (I assume the express version will do, but can't tell for sure). You could also rebuild python 3.1 debug dll with mingw, if that's possible, I suppose. And when using vs2010, you could rebuild the python 3.1 debug dll with that. OK. Is it possible that these dlls get added to subversion? I would update the cmake rules then.

patch [#25972] blender-thumbnailer.py: GVFS support
from Shinsuke Irie (irie) with some minor edits.
Shinsuke's description from the tracker:
---
I have implemented GVFS framework support of blender-thumbnailer.py which
allows some file managers like Nautilus and Thunar to show thumbnails in
trash or network directories. If Python's gio module is available, the
thumbnailer uses it to access to filesystems mounted via GVFS. This
change
shouldn't affect desktop environments other than GNOME and XFCE.
A function gvfs_open() in this patch is defined to solve a stupid
incompatibility between Python file object and GIO Seekable object.
On Ubuntu 10.10, I confirmed thumbnails can be generated for file://,
trash://, sftp://, and smb://.

Re: [Bf-committers] python mathutils api update proposal
I'm importing/exporting a format that uses eulers exclusively, so I can't avoid them. They are also the default rotation method within Blender.

Re: [Bf-committers] Question about bone allocation (Chicken or the egg)
Why are heads and tails stored anyway? This would be a great opportunity to make editbones loc, rot, length. The difference between edit and pose is bizarre from both a user's and developer's perspective, and a huge HUGE headache when importing/exporting. On 01/02/2011 2:13, Tobias Oelgarte wrote: Im currently reviewing the armature code to fix the loss of precession while switching between edit mode and pose mode. Basically the locations and roll angles are computed back and forth every time. Since it is done with floating point precession the rig tends to fall apart. To correct that i will have to know how the Bone struct is allocated. Does it even get allocated? Meaning that it will always be the result from a conversion from struct EditBone to struct Bone? The question is basically about the fact which kind of struct is created first. From using blender i would assume that Editbones get created first and will then be converted to Bones, when you leave editmode. On the other hand: How it is handled while loading an existing file? Are the Editbones (for editmode) stored or the Bones (for Posemode and anything else)? What i basically want to do is to store the untransformed head and tail locations together with the boneroll as separate variables inside the Bone struct. That seams to me the only way to get rid of the steady conversions, which will end up destroying the bone locations in editmode.

Re: [Bf-committers] Removing auto registration
I have several operators in my script and was always annoyed at their lacklustre ordering in search results. Turns out that re-arranging them within the script fixes that problem too. +1 for manual registration! On 24/01/2011 2:56, Campbell Barton wrote: Martin correctly reprimanded me for being vague on the kinds of problems that auto-registration causes, so I had a look into it today :) Started by looking into a registration bug in the tracker by removing auto-registration locally to check if this was causing the problem. https://projects.blender.org/tracker/index.php?func=detailaid=24132group_id=9atid=498 https://projects.blender.org/tracker/?func=detailaid=24498group_id=9atid=498 (the same bug but wasn't obvious initially) In short, it is. Any subclass of an IDPropertyGroup is instantly registered and never unregistered, but this was a known problem. If we remove auto registration editing existing addons to correctly load/unload is not a big problem, I did one script as a test. Though Martins answer is to fix the auto-registration which is all very well, except that I still would rather remove it. The other things are things are less immediately useful. For example registering operators automatically, and removing them at runtime while the script stays running. How would this be done with the current system?, from what I can tell it cant be. @Marin, I think you misrepresent my position in one respect, You say that I would have users solve registration problems themselves. This isn't true, we can have a function which does a smart register of all classes defined. I'm just against this being built into the class. Infact when removing auto registration I added a utility to register all classes in a module because defining class lists is tedious (as we had before auto-registration was introduced). def register(): bpy.utils.auto_register(globals()) This registers all classes defined in that module, scanning globals is ugly but I think we can get a good brief function and avoid class lists. So I don't think this should be seen as a choice between automatic+clear OR bloilerplate+verbose. For scripts which register every class like UI scripts we can have a single function, nicer then having to define a class list. Such a function could of course be extended to do dependency calculation too. Btw, you mention finding the class line in python for errors, python cant know where a class is defined, its just not stored. pythons 'inspect' module just a regex search on the source to find the most likely match, not useful for blender internal texts. - Campbell On Sat, Jan 22, 2011 at 10:56 PM, Sergey Kurdakov sergey.fo...@gmail.com wrote: Hi, I'm sorry, as actually I would need to dig into details to understand all the subtleties, but few sparse thoughts order: is it possible to have a two step registration? such that first - there map is created ( or graph http://www.boost.org/doc/libs/1_45_0/libs/graph/doc/index.html ) like it is done in boost.python (starting files to look at are \boost\python\converter\registry.hpp | boost\python\converter\registrations.hpp ) of types , where all requested types are registered upon class creation and then then the whole system is glued together ( registered ) looking for unavailable parts and the next step? will it solve Matt Ebb and Nathan Vegdahl have complained about auto-registration in its current state fir renderman support which does dynamic generated classes from shaders, and rigify for rig types. if yes. then why two step registration is not an option ( or will it add too much complexity)?

Re: [Bf-committers] New Blender Logo
One thing I'd like is for the Windows icon to be updated to the much nicer Gnome version. The Windows one is all flat colour and looks really boring. On 09/01/2011 3:58, Jonathan Smith wrote: The old Blender logo has been hanging around for (as for as I know) just as long as the UI/Theme has been. And now the UI/Theme has changed drastically, and I wonder whether it might be time for a change to the Blender logo. Although I don't believe we would have to change it all that drastically, I think a subtle change would go over well. The first change (and a more general one) that I would propose for any new logo, would be to get rid of the blue colour, which that circle in the middle currently is. Although originally that same blue (or something near the same) was the default world background as well as being the colour of many buttons, now there is hardly any blue in the default theme of Blender. Therefore to go in line with new theme of Blender, at least a new colour scheme for the logo might be nice, using colours like grey and orange. The second change (and this one would be more specific) is to get rid of the rounded edges on the logo, and on any new shape that people might come up with. The rounded shapes seem to give the logo a bit more childish/not-so-serious look which doesn't seem to meld with Blender's new look. It would be nice to have some sharper edges (I tried to do this a little on the mockup I linked to). All of this is just my own opinion and I would welcome anyone else's thoughts on the matter, to the point of whether or not we even need a new logo for Blender. I understand that changing it would require a lot of work, including reworking at least two of the Blender icons, not to mention the actual designing of a new logo. Another effect of this would be some disassociation of the old Blender icon with the new Blender, instead it would probably strengthen the ties to the older version (2.4x, etc.). This might not be a bad thing though, it would let people know the difference, between Blender 2.5 and Blender 2.4, they could look at the icon and immediately tell the difference. I did some very quick mockups of what a new Blender logo might look like: http://www.pasteall.org/pic/7940 http://www.pasteall.org/pic/7941 *note this is just a mockup, if there was to be a new one, it could use a completely different shape, etc. However I did like the way the colours in this one were complimentary.

Re: [Bf-committers] Windows Explorer thumbnails for 2.5
Great! There was one last bug that I just fixed, which caused drop shadows to be added to the thumbs (bad because they have transparency). Register it again to apply the fix. I didn't spot these problems because I registered it on my system by hand, if anyone was wondering.

I am not sure if I am getting a bug or if I have not understood how this works. I am running Kubuntu 10.10 current SVN Blender 2.5 64 bit I have found in preferences where it says thumbnails and have turned that on. I have rendered and saved a blend using the default cube but even when reloading my blend using Blender I get no thumbnails and I don't see any with Dolphin ether. Help? Or bug? Thanks Kubuntu is KDE, Ubuntu is GNOME. It seems their thumb handlers aren't compatible. ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
