caustics

[bbgrid]

Hi I have problem on the ceiling after I enable caustics (swiming pool plane) with default parameters.
I can tur it off on this view but how to avoid this?

thanks

You can try disabling Environment Importance Sampling to make sure these are not caused by it.
I need to add some more parameters so you can control only the caustics generation of EIS.

Another thing you can try is disabling caustics in the Base Shader.



Then add an item shader, only to the pool geometry, so it will override the Base Shader. This way, only the pool will receive caustics.



With this approach, you need to make sure that any other item shaders also have the caustics disabled, since they override the Base Shader.

Instead of an item shader, you can use a selection tag. Maybe call it "receive caustics". Make a mask on it and put it above the Base Shader.
Then you can tag any geometry that you want to receive caustics with that selection tag.
