I finished my very first high poly model and when i try to ligh it on cycles, no matter the type of the light I use, I can see the model lit only if I tilt the camera so that the surface is not parallel to the camera.
Yeah, this is 100% your material. I don’t understand what you were going for here. Just plug your principled shader into the output and don’t have the base color pure black if you dont want it pure black.
