wall paint and lights

[sukaynabaydoun]

how to make regular wall paint using v ray material, I was trying several times but it always seem not realistic

and lights are the same, I was looking for tutorials but I did not get benefit

Wall paint is all about adding a subtle bump of texture. Otherwise just a plain color with little or no reflection will do it. The reality comes from adding Ambient Occlusion with a dirt pass or rendering it straight in.

 

As to lights... They take time to get the hang of. It's a balance between lights and camera exposure. The best approach is to get a flat dul lighting started then make it brighter with lights that give the scene a directionality and a sense of depth. While you would shoot to be right on, it is better to have a slightly darker render than too bright and then post the magic in.

keep a closeup photo of a real wall and try to emitate it, as said play with bump and reflection to get it right

What they said. I would normally use a VRay blend material, in the first material's diffuse slot I would add a noise (experiment with the tiling) with a small value for bump (between 3-5) and blur of 1.0. In the second material's diffuse slot I would add a bitmap of some irregularities (scratches and dents, black and white and highly contrast bitmap) with blur of 0.1 and bump to your taste.

Keep in mind the wall does not have to be reflective to look realistic (although it helps)- it's the way light falls onto the wall (in conjunction with the bump of course).

Happy modeling.
