I finally had time to come back to this Projekt
I made Studio Lighting setup now. Lights are All dynamic and its a screenshot, so now extranal post and retouching.
@: Danke @TheFoyer: Thanks @renderman.pro: There is allready a HDRI in the Scene, but its a little pixalated because of the 512 restriction. When i have some more time to work on this i will change this in the Engine it Self to get a sharper HDRI.
@m.orzelek: thanks, the car has 230k triangles and one Tyre with all parts has 150k tris. I really didnt watched the Polycount, it originally was a 30k Lowpoly Model wich i just detailed a bit.
