I am using the new simulation nodes to have an object rotate randomly, when the object leaves the simulation node block: all it's materials are gone. I can't seem to find a way to reapply them. There are 2 differrent materials and I have tried using vertex groups to select only the correct faces, but that hasn't worked.

I'm verry new to geo/sim nodes so please bear with me.

the selection input is the material index, I have also tried it as a vertex group. A blender geo nodes tree

This is what it should look like: enter image description here

This is setting the jewel material enter image description here

but trying to add the metal before that stops it from working enter image description here

  • $\begingroup$ pls show at least your node tree so we see what you did ...or provide your blend file so we can check it out. thx $\endgroup$

Issue #108410: Geometry Nodes: Support materials in simulation state.

Currently, the simulation state in geometry nodes cannot contain materials.

What you want to do, is to capture an integer attribute, and then - after the simulation - assign materials based on this attribute.
