Solaris and Karma » reference paths from list of primitive paths

Lets say I'm defining scene structure like in this example and I want to use this defined structure as path references in different nodes, same way as in sop you can create channel reference. That would make sure i can change name in scene structure and auto update it elsewhere since as I understand there are no dynamic links in usd. I'm starting with usd and solaris so I'm not sure if this kind of channel referencing is necessary, but I feel like this would reduce possible errors in paths.

Hi, I'm using primitive node to define scene structure. if I use relative reference it references all paths how to reference single one?
Solaris and Karma » Solars / Karma CPU/XPU domelight issue

Actually found workaround here https://www.sidefx.com/forum/topic/94635/ [www.sidefx.com]
solution for me was to set env HOUDINI_OCIO_FILENAME_COLORSPACE = 3. I have to use kma_ocio_transform after reading texture file, and set From_space "SRGB" and To_Space "scene-linear Rec.709-sRGB", but after that renders look similar
cheers

I have problem with domelight and karma XPU. In this example I've used one of hdri hraven maps. It works fine in redshift and karma CPU. Renders look identical, but karma XPU is different I'm suspecting colorspace issue. Maybe someone had this problem and shares solution

edit prototype seems handy in this case. For now I've used explore variants and after that randomly instanced them, and it worked fine. Thanks for suggestion

Lets say I have animated assets of different models with many different accessories. I'm using this all assets in point instancer as references, and after instancing is done I'm randomizing time offset on instances. Now I'd like to randomly hide different accessories on different model variants. Is it possible on this stage of scene assembly?

The biggest issue for this moment is viewport in solaris and very long time of loading agents. Is it possible to add usd proxy to agent made with mixamo fbx?

Hi,
I have question regarding solaris/karma and crowds. I know there is new Crowd Procedural which is supposed to help with rendering and its fine on small scale, but is it even possible to render really large crowd for example stadium in solaris? I'm trying workflow for crowd procedural as it's suggested in documentation, but i cant load this many agents to lops, even few thousands seems to be overkill so I'm wandering if it's possible to do this. If not, how would you render this?

Hi,
Is it possible to swap rbd simulated object to different one while simulating? For example bunch of simulated boxes changes at random to spheres which inherit position, rotation and continue to simulate.

Hey,
I did it like this:
Hope it helps
I did it like this:
vector4 valueq; int pNum = attribsize(0, "detail", "_orientation"); vector4 _orientation[] = detail(0, "_orientation"); for (int i = 0; i < pNum; i++) { valueq = _orientation[i]; setpointattrib(0, "orient", i, valueq, "set"); }
Hope it helps

Hi
I have alembic with point cloud exported from Max tyflow , and age of particles is stored in detail. It looks like I need to read _age and assign it to corresponding point, but I can read only first value. There is everything in spreadsheet but can't read chosen value. If I use
f@age = detail(0,“_age”,0);
I will get first _age and that is correct but if I use
f@age = detail(0,"_age",0);
I get 0 and that is wrong.
There is different value in spreadsheet on detail _age. Same problem if color is exported it also lands in detail in this form. If Velocity is exported it's stored on points as usually
Scene with simple alembic in attachment.
Thanks

Hello,
I think I have a similar problem so I will post it here. I can't find solution for volume loss in flip after introducing rbd object. I've tried everything, I knew that could help but with no luck. I'm attaching hip file, so maybe someone has some time to look at this, and push me in right direction.
Thanks!
