Title: clamping of relections
Post by: 3DsChobo on 2015-01-14, 12:52:06

in the tooltips of the corona setting it says lowering the max sample intensity will result in clamping of reflections and other stuff.

can someone please describe what clamping exactly means? because i cant find a suitable translation for this word.

It means no ray will output GI values higher than 20. If it outputs 19, fine, if it outputs 21, then the result will be clamped to 20. If it outputs 20000, then the result will be still 20. This is obviously biased, but does not affect the scene much, and removes all fireflies with extreme intensities that would otherwise never disappear.

thanks, that makes it much clearer to me.
