Bump Blender
Introduction
This shader allows you to combine the results of up to 4 bump, normal and round corners shader nodes.
The output of this shader is a displacement vector, which when attached to the material bump-map input will result in a perturbed normal.
We recommend when using regular height-field bump maps, you pre-blend the texture input, which is more accurate and more flexible than using this node to do blending after generating the bump.
