HDRI lighting overbright?

Tue Oct 13, 2015 10:29 am

when adding an Environment Texture to my scene, the background is much darker then the lighting emitted by the map.
how can i match them?
Kernel is PT, Camera response Linear, Gamma 2,2, Highlight compr. 1,0.

What is your exposure settings?
And some hdr backgrounds work with 1.0 instead of 2.2,
Maybe that is now your case a well?

I've noticed an inconsistency in the lighting and the displayed image when using HDR's.

In order to get correct shadows(that match the shadows in the HDR) I have to turn the gamma way up to 2.2, but then the background image is blown out. If I use gamma 1.0, the background image looks correct, but the shadows do not.

Another reason why it's beneficial to be able to specify separate textures for lighting and reflection/background. Mentalray and Iray have this and it's very useful.

Exposure is 1.0
Texture gamma was 2.2 changed it to1.0 now it looks correct; Thanks for the hint!
Honestly, how to use gamma correctly is still a mystery to me....
