MagicRej Posted October 24, 2012 Share Posted October 24, 2012 (edited) Hi Mantra ignores the bounding box object. The render result varies depending on the Mplay Tile Order (vm_image_mplay_direction)" parameter, and not correct always. houdini 12.0.717 Linux64 Ubuntu 10.04 LTS (linux-x86_64-gcc4.4) OpenGL renderer GeForce GTX 460/PCIe/SSE2 OpenGL version 4.2.0 NVIDIA 295.20 Who knows what's up? fur_ifd_bounds.hipnc Edited October 25, 2012 by MagicRej Quote Link to comment Share on other sites More sharing options...

MagicRej Posted October 24, 2012 Author Share Posted October 24, 2012 (edited) fur should be just inside the box only. And we see her outside. Edited October 24, 2012 by MagicRej Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted October 24, 2012 Share Posted October 24, 2012 I think you're misunderstanding the purpose of the IFD bounds. The IFD bound is tell Houdini when to procedurally create the fur and when not to. The bound should cover everywhere there will be fur. This is a render performance optimization thing. If you don't want to mess with it you can simply select the option for "No bounding box required" on the fur procedural. If you want to control where the fur exists and where it doesn't from an artistic standpoint that happens in the network for the fur. See the help for fur which covers it much better than I can in the forum post. Quote Link to comment Share on other sites More sharing options...
Ingvard Posted October 25, 2012 Share Posted October 25, 2012 (edited) Hey guys! Let's try to consider the simpler example - Delayed Load Procedural and its RIB analogue - Procedural "DelayedReadArchive". I'm more experienced in renderman that's why I compare any mantra features with prman. I wrote a little rib and confined the X between 0 and 1 and you can see the result on the attached picture - clipped geo exactly on the bound of X. I did the same with mantra and also confined the X between 0 and 1, but in that case I see in my opinion very strange result. Is it feature of mantra? Does it load procedural differently? Why the result not the same like in prman case? I did the mantra test on Linux Ubuntu 10.04, houdini- 12.0.717.nc dra_ifd_q.hipnc Edited October 25, 2012 by Ingvard Quote Link to comment Share on other sites More sharing options...
