I would also like to avoid using other programs outside Blender as well. Personally I don’t use it because it has obvious limitations and the support seems very small and limited to me. P.s I have seen that some users manage to get the desired result using the LuxCore render engine on Blender. P.s I also tried changing the radius of the light beam but the problem has not yet been solved. I made several attempts but I haven’t solved the problem yet (it’s probably a technical limitation of Blender). This gave me a hint that maybe it’s a mirror material/shader issue. However, while doing some tests I noticed that during the render before the final denoising, some white dots of light were forming right in the area where I would like to see the beam bouncing and passing with smoke in the void between the two walls. Again, volumetric light doesn’t bounce either. To make this problem more evident I activated the principle volume/smoke in the world to highlight the beam of light. Result = it doesn’t work, or better: if I increase the roughness of the mirror surface the “bright circle” of the bounced light starts to appear but the more I increase the roughness the more the sharpness/definition of the edge of the bright circle is lost. – The “caustic reflective” option is active and on “Light paths” (in the “Render properties” drop-down list) I increased the “glossy” and “total” max bounces.


– Blender v.3.3 – I’m using “Cycle” as render engine.
