It works really fine. Acutally, I had to use IES light for a better render and caustics works.

Thanks nuno, i go to try your settings right away!
and about my videocard, it is a geforce GTX760.

It looks to works with a day light:


Thanks!
But I am not a huge fan of the octane day light, I had a better control and a better look with the octane light. You guys always use daylight for caustics render?

For the record, my system unit scale is: 1unit fo 1 millimeters
I know there are some trouble if you use the wrong unit scale, so I also try 1 unit for 1 meters, and it doesn't look better.

Thanks for the reply. This is what I get with your setting:

Hi everyone,

I am kinda new in here, but I hope you can help me.

I am running on the 3D Studio Max Plugin, and I am trying to get some proper caustics. I read to get caustics we have to use PMC, one light emitter, but still, i can't get any caustics in my render and i don't see why. Please enlight ...
