   Hmm…following this exactly & I’m not getting the spot effects on the wall. Is it due to my lighting angle or rendering angle? Is there a specific material applied to the background wall that allows for the Photons/Caustics to show?

   Hello shepherd,

   The image was rendered using the Photons> PT Caustics Fine preset. Please render with it and tell us if you see the spots. I will make that explicit in the tutorial.

   ¡Thanks for the heads up!

   Did it that time & I just got 2 large sharp grey circles (assuming photons) on my back wall. Does my back wall need a material? Is it incumbent on my light angles?

   Light angles have an influence, so I would play a little with them, and the wall distance also plays a role. The nearer the walls are, light spots should be brighter and better defined.

   I will try that! thank you.

   Let us know how it comes out!

   No luck! Must be me doing something wrong. I have my material set exactly for the disco ball. I have 2 spot lights set up & my lightdome set to Physics w/Orientation & Reflected checked & Ambient unchecked. Intensity at 100. My back wall is set up w/no material & have tried different distances from the disco ball w/similar results. It looks like it wants to give me some photons, but it’s generally 2-3 solid sharp circles on the wall, no color in them. I’ll keep trying. Is there any settings applied to the wall in the background (material?)

   I added the example file. It is linked at the bottom of the tutorial in case you want to inspect it. There is no texture at all on the wall.
