Hello guys, I have such simple but tricky question.

I have an awful base geometry but with correct UVs. I am now trying to transfer some attribute from the particle simulation to the shader, but of course I can't use the actual geometry to transfer attributes, I need to use UVs to preserve detail. Do you have any solution for this?


Thanks a lot for your time

not sure if you can sample geometry during Redshift render as you can in Mantra
but you can definitely bake it into textures before, using Bake Texture ROP

Might be better off using pointcloud lookups in a vopcop, using uvsample() to get the position.

Maybe, unless you need UDIMs, then baketexture with point cloud lookup in the shader may be easier

Well, thanks for answering! But, how can I take the positions from the particles and find the correct uv coordinate on the geometry and “”flag“” it with some attribute that i will use in my shader?
