I'm thinking about a more realistic material reflection like it is used in other games like Forza, Wreckfest etc. I know that the aim is actually not to improve the look of the game (at least at the moment). But if there is a possibility to include this so called Fresnel-effect in the game engine of BeamNG in car-materials it would enhance graphics and performance a lot! (especially 11:58) This is actually explained for blender, but of course you can transfer it to BeamNG... The main message is, that the angle to the camera actually decides how strong the reflection actually is. Compairson: Hope it helps!
