I have found a problem with reflection brightness and AA. Is this a known problem? It should look like this ![](https://europe1.discourse-cdn.com/chaosprd/original/4X/a/a/4/aa43dbce057a7ba54e039662f55852d0c84fc699.jpeg) with higher max numbers it looks like this ![](https://europe1.discourse-cdn.com/chaosprd/original/4X/d/8/4/d849b8886c32c22b9a5ae28b343b830cecb5a2f4.jpeg) with a adaptive subdivision it looks fine again ![](https://europe1.discourse-cdn.com/chaosprd/original/4X/6/6/c/66cf25d4d159de72c7ece86efe5a35abd5f10a17.jpeg) any ideas why this happens? best regards themaxxer ---

It would probably help if you turn off color clamping in the Color mapping rollout - if that doesn’t help try also switching to Linear color mapping. Best regadrs, Vlado ---

hi vlado hm, the clamping is off. I have to try the thing with the linear color mapping… best regards themaxxer
