Caustics effect’s problem

[Emmortal1]

Unlink the light that is emitting the photons that you don't want to effect on the surface and turn on Photons Obey Light Linking in your render globals.

Another way is to:

1. Select the object

2. Open the Attribute Editor to the transform node's page

3. Under the Mental Ray section untick the "Derive from Maya" box.

4. Change the "Caustics" dropdown setting to "Disabled" or "Cast Only".

Hi guys,

I’ve still a problem….

I’ve tried both your solutions; I’ve linked my caustics-spotlight (this spotlight has the Emit Diffuse, Emit Specular uncheck) only to the glass borders and checked Photons obey light linking, and I’ve even disabled the caustics, using flags, for the box’s glasses and for the wall behind the box, but, as you can see in the figure:

the glasses saturate (The main light is a pointLight in which I’ve placed Caustic Photons to 0). Any suggestions ? :hmm:

Bye and thanks
