  1. Hi! did anyone experience the same issue? I imported an Alembic file with different face IDs to Houdini. But when I export it back via Alembic just for testing the ID grouping is basically right, but they don't have the correct order/ID… , they are randomly distributed. I cannot see any pattern. It's neither alphabetically nor based on face count. My node tree consists of: Alembic Import Node –> ROP Alembic Output. On the left side you see the original mesh with correct Material ID order and on the right side the imported Mesh with the wrong material order. Does anyone has a solution for this? Thanks in advance!

  3. Hi, I'm trying to render with objectID aov in Arnold. I haven't used AOVs yet, so I'm a bit confused and the arnold doc is very meeeh about that. Do I have to make shaders for the aovs ? How do I set an ID to an object, or a group ? I'm still trying out ... but any info would be great.
  4. Hello guys, I work whitewater for splash. I made a whitewater source particle. I want high velocity pariticle delete. So I made a high velocity group made. However, The pariticle are removed from the group while slower speeds. For example is parabolic movement. But If I want to continue to maintain, including once in the group based on the ID. I try it use sop solver. but point count changes does not work. Is there any way what? Many thanks, Hyungi Jeon.
