OBJ's inverted in Mari
Hi list, I was wondering if someone else got this problem; OBJ's exported from Soft sometimes get objects weirdly inverted so they can't be shaded correctly in some other programs, one of them is Mari. I can still paint on the objects but the shading doesn't work. Same OBJ's display problems in other software too so it's not just Mari. The objects tend to be those that were mirrored in modelling, but not always. I'm wondering if there's something I can do in Softimage to get it to export everything correctly? I've tried the few options that the OBJ export has, doesn't seem to make any difference. Creating subdivided meshes and importing those seems to help, but not always. Exporting the same objects to Alembic works fine in other software, except for Mari which doesn't support it. Can't find a peep about the problem on the net, and we're getting it here consistently, I'm just guessing it has to do with Soft's OBJ exporter or something with Soft normals. Any solutions out there?
Re: OBJ's inverted in Mari
Is the object at the origin? I recall that I DID have a similar problem in Mari but it was more to do with some weird inverted lighting because it was far from the origin.. But as you say you are having issues in other programs too..

Re[4]: Attaching curves
Thanks! Backup needed here, though... I got cautious saying the N word (Nurbs), because then the usual associations of them being legacy tech kick in, and everybody turns his back quickly. This is about being able to use CURVES mostly (which happen to be Nurbs, too), and which are a fundamental modeling asset. ICE cannot deal with them properly. If anybody else finds it as ridiculous than me that not even a handful of BUGS (not tools, features, workflows) get tackled in that regard, so we can at least happily write and use our own tools with success, you might want to tell the devs. Like surfaces, too? (I do) - Please also tell Autodesk. The only outcome of that ridiculous petition I started last year for better Nurbs only lead to the lapidary comment of Cory Mogk: we can't make everbody happy.

Re: how to obtain full script editor history
if that preference doesn't work for you, there is nothing else. check if you can open the file while XSI is running using file sharing flags (something like SHARE_READ), and not just the default sharing flags (which is deny everyone else) the only recourse you have IMHO is to work write your own logging system, which means an EndCommand event to log commands and also sending the output of your tools to your own file rather than stdout or silogmessage.

Re: Redshift3D Render
FWIW, I've done some pretty heavy archvis-type scenes with Redshift. Several million triangles (usually straight out of CAD, so, yuck), a few hundred ray-traced area lights, an HDRI dome, about 50 MB of textures (so not very much there), TONS of procedural noise textures, bump maps on most surfaces, up to a couple million instanced small objects with emissive materials, with depth of field and motion blur, for HD and print resolution, etc. RS has chomped through all of it in very reasonable times and without ever challenging the memory limit on the Titan. Can't share any scenes or images though. :-( One note on the expense of a Titan -- I have a pair of them in an early-2008 4-core Mac Pro Bootcamped into Windows 7. For a proper lighting/lookdev station running VRay, Arnold or Mental Ray, I would have to spend well north of $8000 on CPU RAM alone and still wouldn't have more than a fraction of the performance. The Mac Pro could be had for under $2K (although it was free to me as I bought it new and it's been fully depreciated) and the pair of Titans for about the same. By upgrading only GPU instead of CPU chassis, companies will be able to double the lifetime of their CPU purchases, perhaps more. And the upgrade cycle costs will be significantly lower per-seat. The Titans certainly paid for themselves on the first project they rendered. I'd feel differently about the changeover costs If I already had a sizable render farm, since most of the blades and 1Us that people have invested in can't even carry 1 GPU card. But if you are building out a new place or growing the farm, you can pick up 1U servers built for Tesla-style GPUC clusters that have power and slots for 3 beefy cards. Since you won't care too much about CPU specs, you can buy ones that are being retired on the secondary market pretty reasonably. Once it can handle ICE attributes, I'll have no reason to look back, EVER... Also, someone was wondering about SLI -- RS doesn't use it; it handles multiple CUDA cards just fine without it, even if they're very different cards.

The user was free to move between built-in methods such as closest location, raycast, closest vertex, ... as well as other custom criteria I devised myself.

I'm wondering if I should just bite the bullet and paint the weights manually at this point via numerical input. It's a pain, but right now I don't know of any other method that wouldn't be overly troublesome, short of modeling the hidden polys again and combining them back into the body mesh. The lack of ability to mirror weights on the head is going to be a real pain to get the rig to behave symmetrically though.

The exact line that is referenced,line 654 seems to reference timecontrols, but I don't understand how that would affect the creation of a simulation region on a point cloud. Searches aren't yielding any fruit. Has anyone run into this and found a way to get rid of the issue? Adam

And symmetry mapping errors The problem is...my mesh is already split up into pieces when i was starting to weight them. The full body mesh doesn't exist anymore, the hidden faces are already gone. :X Also I tried duplicating all the geometry and merging it together while trying to preserve the existing weighting so I could continue working on it and then GATOR the weights back to the seperated geo later, but merging the geo together even while transferring all attributes seemed to remove the weighting from the character entirely... I'm wondering if I should just bite the bullet and paint the weights manually at this point via numerical input. It's a pain, but right now I don't know of any other method that wouldn't be overly troublesome, short of modeling the hidden polys again and combining them back into the body mesh. The lack of ability to mirror weights on the head is going to be a real pain to get the rig to behave symmetrically though. Hopefully the paint tools get an update eventually for this sort of thing...I never even knew painting across multiple meshes was an issue, no wonder it's recommend to model unibody in XSI. Oh well, something new every day! :P Thanks for the advice all! Yours sincerely, Siew Yi Liang On 2/17/2014 3:14 AM, Greg Maguire wrote: This is my preferred method too. ILM had a really cool concept I'd like to see in Soft. Instead of painting with the radius of a circle, make the brush three dimensional like a ball. Wings can be tricky, I generally chop the top or bottom part of a wing off and Gator everything. However a 3D ball would remove that need. On Mon, Feb 17, 2014 at 11:08 AM, Mirko Jankovic

animating instances in place of hairs

btw... I should note here that I am aware that I can scale the guide hairs and animate that scale. I would like to animate the shape of the blade of grass, as well, using the shape animator.

If you scale in other axes besides Y, does it work? If not, what about scaling the points instead of its transform?

Re: animating instances in place of hairs
The scaling of points or shape seems to work, but the result is then scaled over the entire guide hairs. I am trying to override this. I can't even figure out how to rearrange the stack so that the scaling of the object or points is done after the object is scaled to fit the guide hair. For instance... if I scale the grass blade (the instance object group) in Y then the grass field has short fat blades that go the entire height of the guide hair. If I put a deformation cage on the blade, it does deform, but is then stretched to fit on the guide hair in y.

Setting a particles mass based on its instance size
Evening again everyone, I'm looking for an attribute that lets me read in each particles instance size / scale, so I can use it to drive per point mass. I am using Momentum deform bodies and wanted to drive my mass based on the chunk size. Not sure if this would be the same situation for regular instances. I wasn't sure how to look up instance size, or calculate it. Anyone have any ideas on how to go about this? My first thought was to read collision size, but it returns an error. I don't see any other handy ICE attribute I could leverage. Thanks for any thoughts Adam
