No, it should not be visible. Maybe a bug in the depth of field code (could it be that it generates some rays that start below the ground plane?).

It's not implemented yet.

(I guess you mean OpenCL, not OpenGL)

• Is this with the latest alpha5 version?
• Are you using the latest graphics card drivers?
• Can you post a small example scene that crashes on your PC?
• Does it happen every time you start a final render or only sometimes?

I also want to thank Philstix for contributing a handy node with IOR presets.

The big instance is a bug in BlendLuxCore (that I already fixed). It is caused by the following: - the dupli object is exported once without any transformation - This is then passed to a fast LuxCore function that duplicates it a few thousand times - At last the original, un-transformed dupli object...

I take it that Cycles (or other renderers) do not crash? Do you have overclocked components, changed RAM timings, undervolted components or anything else like this which could cause system instability? You could also try running LuxMark and see if that also crashes. Also make sure that you have the ...

By the way there is already an old issue for this feature: https://github.com/LuxCoreRender/BlendLuxCore/issues/32
So I won't forget it.

When I change the unit scale to 1 it seems to work.
Probably some matrix is not getting scaled by unit scale, I'll investigate.

Dade: Do you know a good way to make a non-invertible matrix invertible? My naive approach: l = [matrix[0][0], matrix[1][0], matrix[2][0], matrix[3][0], matrix[0][1], matrix[1][1], matrix[2][1], matrix[3][1], matrix[0][2], matrix[1][2], matrix[2][2], matrix[3][2], matrix[0][3], matrix[1][3], matrix[...

Yes, but it's not yet exposed by BlendLuxCore.
