Random per island help please

Post by sarmath » Thu Oct 15, 2020 1:19 pm

Hi

I am trying to use random per island in Blender 2.83 and luxcore 2.4 and it seems to not work for me.
This is test scene, can someone confirm what I am doing wrong or is it somehow broken thanks.

The random per island shape code performs a "merge doubles" operation before detecting the islands: https://github.com/LuxCoreRender/LuxCor ... pe.cpp#L43
This should probably be removed for this shape (Cycles doesn't do this).
