As I mentioned earlier in Hammer's thread I think caustics would be a nice addition to TC. A while back I played around with faking caustics and found that a projector or area luminance could produce a fair result. The attached image uses an area luminance attached to a copy of the diamond. Shadows are disabled on the area luminance, so the render time really isn't negatively affected. I know the result is completely inaccurate, but still adds to the image in my opinion. Any thoughts?

I've done the same thing on occasion, Brad.

I like that Henry. I'm getting thirsty though. What are we having?

That's a great looking diamond Brad.

Did you create the diamond model as well, or is that the one Henry had posted a while back.

Thanks Don, I believe Alfred Kypta posted this one. I could be wrong though.

Brad and Henry those are both very creative work-a-rounds. That is where imagination comes into play.

Lovely diamond, nice workaround

Hi Brad,

beautiful effect, it only remains to hope that the next Lightworks engine will also think of these technologies. That there was no need to seek alternative solutions.
