I've tried and it doesn't work. What are my options? Correctlly unwrapping my geo is impossible i think. I was counting on Triplanar and now I'm in trouble.

Sorry, I'm afraid that there is no solution for this limitation yet. That's a common issue with all projections other than UV. Right now the only solution would be to bake the Triplanar Mapping to the UV, then use the result with a UV projection.
Triplanar projection is definitely dedicated to static or animated/non deformed meshes.

Hi guys,

Still no solution to this? It would be super useful to stick the triplanar projection result to the mesh / UVs without the need to bake!
If there's no solution, a follow up question: Is it possible to bake the texture to UDIMs?

Thanks,

Nope, not yet, sorry. The support of the "rest" attribute is planned for Octane 2022.x, so hopefully, this could help with this issue.

Looks like the OSL solution proposed in this thread is working:

I agree with FakePilot on this one. While Redshift can have a Triplanar projection on deforming objects using a @rest attribute, Octane still misses this feature.
I think this feature should be suggested to Octane core devs again.
