Re: [Bf-committers] [Soc-2012-dev] loss of data after fbx-import and reopening of saved file
Ok, I can confirm that the issue seems to be about this „Object usage counter“. Going to the Datablocks-View in the outliner the user-counter for every mesh is 0 but is 1 for the parent objects/empties. (see screenshots:) I can't set this counter to 1 manually but use the “fake user” button. When I use this for specific meshes or objects it saves exactly those meshes. But it would be a bit tedious to do this for every mesh. So I found a little workaround for the moment to set every counter to 1 with one action. 1. import fbx-file 2. Deselect active Selection of imported objects 3. Select everything (A) 4. Use one of the Transform Tools of the Object Tools and perform any translation. 5. Undo the Translation (Ctrl U) The Object counter is increased to 1 for the meshes and I can save the file or start editing it. cheers Benny Christian Monfort monfort.c at gmail.com : It makes me think of Object usage counter (don't remember the exact name, but it's field us in struct ID) not being incremented. Each time an object is used in Blender, its counter is incremented (and decremented when it's dereferenced). For example, if you assigne material1 to a mesh, then material1 counter is incremented, then if you replace material1 with material2 in same mesh, material2 counter will be incremented while material1 counter will be decremented... Each object with a counter reaching zero IS NOT SAVED when you save the .blend file, but it's still there in running Blender. If you reload the file you just saved, then all those objects are gone because they were not saved.. and that's why there is fake user buttons, to manually set this counter to 1 and be sure object will be saved. 2012/9/4 Alexander Gessler alexander.gessler at gmx.net: Hi Benjamin, bf-committers, soc-2012-dev sorry for the late response, I was off and busy for some days.

Re: [Bf-committers] CUDA not compiling after tomato branch merge
There seem to be 2 separate problems, one of them caused by GCC 4.7, the other being own Blender bug. r50469 should hopefully fix at least the second issue with CUDA compiling. It's a bit difficult to test this for all potential compiler+backend combinations, so please write here if you still encounter problems other than the identifier __atomic_fetch_add is undefined On Fri, Sep 7, 2012 at 10:55 AM, Tobias Oelgarte tobias.oelga...@googlemail.com wrote: Same error for me on Ubuntu 12.04 64bit (sm_21) with svn up.

[Bf-committers] Minimal hardware spec: SSE2
Hi all, It seems to get become complicated to make a non-SSE build for blender, especially because OpenEXR now defaults for it. (We are receiving bug reports about it). Several newer components in Blender benefit from having SSE2 (like Cycles). BTW: SSE2 was introduced in 2003 by Intel (Pentium 4 ) and in 2004 by AMD (Athlon 64). Every system you bought in past 6-7 years should support this. Proposal is to drop official support for systems older than Pentium4 now. Even when it might still be possible to get it compiled or running - I'm talking about *official* support - in releases and for reports in our tracker. Is that acceptable? Next sunday meeting we can formalize this as a decision.

If we really need to run Blender on a system that is older then that then perhaps they should just download an older version of the software. Even on my system Blender has become so advanced that I am feeling the need for a new system to run Blender. This is super true when we are talking about cycles because my graphics card is to old and I must use the CPU and that really sucks. So anyway I say go for it. Even on my old system it would be good if this means a bit more speed.

[Bf-committers] CUDA not compiling after tomato branch merge
Latest svn up fixed the compile errors, but CUDA still isn't actually compiling :( When I run make -j4 it compiles smoothly but when it gets to the CUDA kernel it seems to just stop after about a minute. Top says that the biggest process at that time is called 'be' and that it is taking up about 25% of the CPU and 88% of RAM??? I left it for about 30 mins and when I checked top again, it said that the process 'be' was using about 3% of the CPU and 88% of RAM. Usually the whole process takes about 10 mins. I think tomorrow I'll try deleting the build folder and compile Blender all over again.
