can you then maybe explain to me some basics to gamma correct reflections?
when i am using your car shader and gama correct it it looks very bad.

a different question. i can not open poser now so i dont know if this is already possible. can we make an object in poser HDRI? for example i make two balls. one has reflection and the other one is bright red(like a light). can we somehow make objects in poser HDRI? so that in the reflection the ball is super bright?
