You could couple 2xUVs (i.e. multiple UV sets) to store up to 4 values for each vertex but it sounds ultra complicated.

Doing it the good old way with Google Drive ! I added a simple plane with some noise to get the caustics. Other than that I changed nothing in terms of settings.


I'm not sure if you are really aware of what ...

So I've added both Light-Tracing and Caustics cache to be sure, and after multiple attempts it still doesn't work. I won't be able to attach the file as it is too big but I'll bring an image of the render and the caustics pass.


Car paint is a glossy material and glossy material caustics are ...

You may need to compile luxcore.dll with debug symbols in order to have readable stack trace of the crash (and know where inside LuxCore it happens).

That's how I create [...] scenes

"That's" ? Where ?

How do you create the scene object ?

You are deleting objects in the wrong order. You are deleting objects while they are still referenced by other objects ("config" is referenced by "session", etc.). They crash can or can not happen, it depends if the broken pointers are referencing memory that has been reused (for your process) or ...
