Thanks to @sarmath and @DEBIHOOD for fixing this scene!

I'm still mixing rough and dispersive glass for better reflections:

How did you get the incoming beam to show up?
I tried to fix that yesterday, but failed :?

I have no idea :oops:
I just took this file and modified it:
Luxcore spheres blend.7z
(604.43 KiB) Downloaded 20 times
I think darker tile colors help the beams to shine.

It looks also a lot better in my opinion.

When I switch (in my version of the file 4 posts above) to Hybrid I can reproduce the missing initial beam.
And also the caustic beams get way too bright (compared to BiDir) :?
No matter if CPU or OCL, with and without rough glass material component.

It sounds like a wrong world volume setup :?:

There is a fog box around the room, the camera and emitters are outside and no world volume defined.
When I define one and assign it as exterior to the fog box and the emitters, there is no change in rendering, still no incoming beam and the caustic beams are too bright.

(I think @FarbigeWelt has somewhere tested BiDir against Hybrid with lasers and volumes and found similar inconsistencies.)
