Re: Industrial underwater scene with caustics and dispersion

Thanks! Render time was not an issue - that dual Xeon server doubles as electric heater anyway :) The caustics cache seemed a bit noisy to me, but that probably could be corrected with adjusting settings a bit. Fog would add depth and with proper light placement create rays of light going through th...

Industrial underwater scene with caustics and dispersion

About 60 hours render time on dual Xeon e5 2690 v2 with Metropolis BiDir on LuxCore 2.5 alpha. Modeled with Blender 2.90. Dispersion makes caustics look really alive.
Big thanks to Dade and B.Y.O.B. for fixing problem with LuxBlend exporter!

Re: No internal reflections inside Glass material

I've just tried a very similar setup with Lux 1.6, BiDir and Glass2 material, and it renders perfectly. Maybe it's a bug in Glass material?
Note how the checkerboard above water is distorted and reflections are way brighter.

Re: No internal reflections inside Glass material

Thanks for help! I'be been trying to do an underwater scene with LuxCore, and I've been stuck on it for a week now. I've fixed the problem with volumes, and while the caustics look even better now, but the water surface is the same as it was. Parts that are above the water are just dimmed, but not d...

Re: No internal reflections inside Glass material

I've also tried creating two-sided material with Mirror as back material, but nothing changes.

Re: No internal reflections inside Glass material

Yes, in the underwater example camera volume is set to water, and in the example with camera above the water level it is set to air. The normals of the water mesh point upwards, interior is set to water, and exterior is set to air. What is surprising, is that while light gets distorted when in passe...

Re: No internal reflections inside Glass material

Also when camera is above water, everything below water is distorted, as it should be, but with camera underwater, things above water are darker, but not distorted.

Re: No internal reflections inside Glass material

I've tried again, this time instead of bidir I used Path + Light Tracing + PhotonGI, but the effect is nearly exactly the same. If I invert the setup - place camera above the water, light underwater and change camera volume to air, then water reflections look amazing. When camera is underwater, the ...
