Category: Bump
Shader Type: Texture
Output: Vector value
Bumpmap produces the illusion of an unevenness across surfaces that are actually geometrically flat. It generates a modified shading normal based on an input texture or render tree. It does this by computing a gradient by sampling the input texture around the point being shaded.
|
Bump Enabled |
Enables or disables the bump shader. If disabled, the bump is controlled by whatever is connected to this node’s bump input. If nothing is connected, no bump is computed. |
|
Bump Scale |
Scales the intensity of the input map for less or more exaggerated bumping. The value can be negative to get inverted bump map from the input texture. |
|
Sample Spacing |
Indicates how far apart (in SI units) the input texture should be sampled. Larger values result in a blurrier map, while smaller values give a sharper result. |
The Bumpmap shader should be connected into Bump Map port of a material node.
To define the bump across the surface, connect an image node into the Bumpmap’s input.
To chain multiple bump maps together, connect another Bumpmap shader into the Bumpmap’s bump input.
