Best caustic pool

[Buzzz]

Hi all,

I need your help to improve the caustics of the pool. The sun size 2.0 and capture the configuration.

How can I have better caustic?

Regards and thank you!

The Corona devs are working on a new Caustics solution, until then, you have few options :

1 - Try to increase the Max Sample Intensity, it will bring brighter caustics but longer render time and probably some fireflies.

2 - Go in Settings > Developpment/Experimental > Change the "Render Engine" to Bidir/VCM or PPM. It is not a reliable solution but might work in your case.

Thank you!

Better with PPM, but not enough.

1h render, with dual v2680 v2 (40 threads)

I can´t modify Max Sample Intensity with PPM.
