I have modeled some object Items, applied a glass shader and am unable to get caustics to show up when light passes through the objects. I am sure it is something simple, can someone point me in the right direction?

Thanks,
Thelby

Caustics settings:
Intensity: 167%
Photon Count: 40000
Filter Size: 66

The caustic effect just are visible in some right camera angles and with correct light

Ah, I see, Very Nice. So the caustic tick is in the render room that's why I could not find. I have looked everywhere else!!!! Thanks So Much!!!! I go and look now!!!

Yes, the idea is the same as projecting a shadow, if the light is in a strange angle you will not see it. So think in a light rig that can project the light throught the object hitting a plane... Dont forget to turn Caustic on in the Render Room.

 It's often beneficial to experiment with the intensity and photon count sliders in the Caustics box of the Rendering tab. The default settings aren't necessarily the best for verisimilitude. 

 I wish I could figure out how to completely eliminate flicker of caustics during animations. Perhaps it can't be done, but I suspect it's a matter of finding the proper settings (and enduring slower render times.)
