  • Caustics direct visualization option

    Can anybody tell me if direct visualization should be enabled for final rendering of caustics? I get 2 different results when it's on and off and I'm not sure which is physically correct. Please see below:

    It should be used for preview purposes only, disable it for the final rendering.
    I'll make a note to add that into the Docs.

      That would be nice. It was not really clear from the docs to me. Thanks for the answer!

        Would it not make sense if the "Direct Visualiation" were just visible during the photon map calculation but did not affect the render? That way we would still be able to see it, but we would not ruin our renders with it.
