I'm not sure, Here is the renderfinal.
Code: Select all
void MaxToLux::renderFinal(luxcore::Scene &scene, TimeValue t, Bitmap *tobm, FrameRendParams &frp, HWND hwnd, RendProgressCallback *prog, ViewParams *vp)
It should work, the argument is declared by reference.
I will dig a little bit more maybe I made a mistake in other arguments.

Try to post a debugger stack backtrace of the crash (i.e. where in the Scene destructor is the crash).

Note, if I had more objects with multi-materials in the scene it is more likely to reach the error. the render itself continues and the problem is when canceling the render.

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).

Found the issue, it was a wrong number of UV parameters, in 3dsmax UV is a Point3 variable and has 3 values for u,v, and w, as I rewrite all mesh functions I did not notice the difference between the 3dsmax Point3 variable and LuxcoreRender Point2 UV parameters, because of that I had 1/3 more value than UV input should have, so base on an object and UV setup I may or may not face the issue.
The problem is solved now.
is there any way to add w in UV for luxcore as maybe 3dsmax users what to use it?

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

No problem it's not that usable feature in 3dsmax, by the way, is there any limitation to the number of UV channels in LuxCoreRneder?
