Thanks for reporting this, maybe Dade can look into this and maybe fix it?
Caustic cache shouldn't get decreased when combined with indirect one.

I replaced the tile texture so we can make this into an example scene.
Also added dispersion as a test, I like it (maybe make it a bit more subtle).
Not finished yet, have to tune the materials and lighting a bit (env. light is a bit too dark).

Just a denoised low sample render because my notebook has a weak CPU, tomorrow I get access to my main PC again.

That scene looks very cool. Too bad the volumetric light is way too slow to render.

Good idea to add the sculpture!

@ epilectrolytics
This must have been some serious render time :shock:

BiDir 1200 samples + OIDN = 3h on Ryzen 2700X
Also there is a procedural bump texture not helping with the speed, so yeah, not animation ready...

@epilectrolytics nice result, would also make a good example scene on its own!

Here's a longer render (around 1h 20min) with larger resolution on a more powerful computer, 1300 samples + denoising.
I tuned down the dispersion a bit (from 0.003 to 0.0015).

Thanks, I'm still experimenting with materials and will report back when satisfied (will take some time because of a current animation render).

Good job with the pool scene!
