Industrial underwater scene with caustics and dispersion

Post by 74hc595 » Wed Sep 30, 2020 1:52 pm

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!

Thanks for sharing nice caustics and details. ;)
BTW why not caustics cache ? (should be faster to render)
And you miss some volumetric foggy effect to make it more appealing.

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 the water, but it made caustics look a bit dull.
In real life very clean water doesn't have much of a fog effect at all. I was on tour of a research nuclear reactor once, and when looking down on reactor core that was submerged in 7 meters of demineralized water there wasn't much fog at all, just a nice glow of Cherenkov radiation.
