Caustics render element

[Jiri.Matys]

Hi,

I have a pool and render it with caustics. I try to enable VRayCaustics render element to make adjustement in PS. Caustics in this element are only reflected on a wall, but not shown on the floor of the pool below water, so its useles. Is this normal?

It is normal. You will need to set the "Affect channels" option for refractions in the VRayMtl material to "All channels", otherwise the caustics element will not propagate through the refractions.

Best regards,

Oh, thank you Vlado, dont realize that.

One more problem. Iam using VRayMtl with FastSSS2 in Blend material. So caustics is still not there.

Then we will need to take a look at the scene. Can you post here or send to support@chaosgroup.com ?

Best regards,
Vlado
