Title: Caustics issue - liquid in glass
Post by: mvshabeer on 2020-05-10, 10:45:22

Hi

I have tried the caustics solver in the V6 daily build. But it is giving me the following issue. See attached

Liquid (Orange juice here) is turning dark when refractive caustics for glass is turned on,

Any workarounds?

Thanks

Hi. Let it render longer, and it'll brighten up. That's the way caustic works. You'll see the same with pool water.

I explained it here:
https://forum.corona-renderer.com/index.php?topic=29402.msg170201#msg170201

So the possible workarounds for now are:
- Disabling caustics for the glass (glass will not cast correct caustics, but the juice will not be dark)
- Using clear material for the juice (e.g. apple juice or clear water) - then you can enable caustics for both and it will work fine
