Thanks for advices guys - hey were really helpful. What I found out so far: with help of reflection captures you can create really good looking scene. I do not have any problems with specular effects. Concerning chrome material: I found out it was affected by post processing volume (rendering features-> ambient cubemap->intensity). I was trying to use it as ambient light replacement, because sky light does not work as good as I was expected. I have a room with three windows and a directional light… plus skylight… and damned room is still dark. With sky light I can make it brighter, but dark objects still are too dark… it needs some minimum ambient level. So, above ambient cubemap works well, it increases ambient lighting, but problem is for whatever reason it affects reflecting surfaces and adds some white tint, making them dull and grayish.
Can anybody advise, how to increase ambient level without ruining reflection?
