It seems to be related to a Vertex Color Group present in the object, if you remove it, the crash does not happend.

Not sure why is it related with subdivision and displace, but it's making LuxCore crash, I'm not using it in any way in the shader.

I can reproduce it. Maybe a bug in the shape execution code?

Sometime bugs are odd and easy to fix (check the patch linked above). I should have fixed the problem.

Hahaha these are the best bugs to fix... when you catch them 👍
