I've been trying to figure out volumes and caustics in LuxCore for the past week or so but nothing seems to work in my case.
I have a scene with a simple prism and a laser: a classic dispersion scene. I have two issues with it though:
- The reflected light from the glass is much brighter than the light emitted from the laser (to the point where it's always pure white and overexposed). The emitted light is fuzzy and creates a lot of noise while the reflected light is pure and really looks like a laser.
- The SDS issue where I don't see the light inside the prism. I tried using Bidir, enabling caustics cache, using volumes, not using volumes, but nothing seems to work. The only hack I could come up with is to clip the top face and literally look inside, but it's only that: a hack (not shown on the attached render).
Thank you!
