P.S. going to check volumes absorption code, I have the strange feeling it may be something wrong.
Note that BlendLuxCore is implicitly creating a colordepth texture for the "Absorption" socket:
https://github.com/LuxCoreRender/BlendL ... __.py#L126
Maybe you mean that?

What I find weird in this scene is that the incoming laser beams are not visible. Or am I misinterpreting something?

Yes, that it is what I'm looking into.

Had set the scale to match real world (1:1), Laser 1cm, volume definition as suggested by Dade... 2min later:
luxCore-1_Render Result_slot_3.jpg
then fiddling some more cuz... oh, where are the lazers?
luxCore-1_Render Result_slot_8.jpg
ahhh... there they are. :o
Maybe because they were set to 0 W & 0 efficiency ;)

Edit:
Q: Is it possible to implement Rectangle shape for Laser?

Ah, got it, the world has no volumes so all the rays starting from the camera travels into the void. The solution is to set the default world volume (or to set the prism and all other objects outside volume).

Well, yes but you can achieve the same result with a quad light source with the emission angle (i.e. theta) set to 0.

I really need to add support for the default world volume.

Oh, sorry for my ignorance... is that a mesh light with emission shader & angles yet to be be exposed in blender or do i have to manually edit the scene file :oops:
