![]() Try using different sized bump, different high/low levels, or combining Regular and Fractal Noise. Variation is what makes things look more natural. Combine areas of high frequency detail combined with low frequency detail like contrasted shapes and blurry shapes. The idea is to try and break up the mathematical look by making it more random. Fortunately you can make it look more random by combining multiple Noise maps or using Mix and Composite nodes. Again, a pretty low Bump amount is needed and there is no need to adjust any other parameters of the Noise map except for it’s size.įor other uses (custom masks, reflection/glossiness maps and other bump effects) a single layer Noise map is too basic to look realistic. You can also add very small scale Noise as Bump to simulate the orange peel effect (very common on painted or lacquered surfaces). Here is an example of this subtle effect in action The bump amount needs to be pretty low to look realistic. ![]() Use a large size value (relative to other texture detail) and leave the rest of the settings alone. Since nothing is perfectly flat, you can make any material a bit more realistic by adding this type of Bump. One of the basic uses for Noise maps would be adding a large scale distortion to a shader.
