Create Bump Map [CBu]
The CreateBumpMap node
Create Bump Map Node Introduction
The Create Bump Map node converts a grayscale (height map) image into a bump map. Unlike
the Bump Map node that turns an image into a 3D material,the Create Bump Map node creates
bump vector data and provides the output as an RGB image so other image-processing
operations can be applied.
Input
The Create Bump Map node includes two inputs: one for the main image and the other for an
effect mask to limit the area where the bump map is created.
–
Input: The orange input takes the RGBA channels from an image to calculate the
bump map.
–
Effect Mask: The optional blue effect mask input accepts a mask shape created
by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools.
Connecting a mask to this input limits the creation of the bump map to only those
pixels within the mask. An effects mask is applied to the tool after the tool is
processed.
Basic Node Setup
The Create Bump Map node accepts a 2D grayscale image like a fast noise, which can then go
through various 2D image-processing filters to create the bump map texture.
A Create Bump Map node produces a bump map as
an RGB image for further image processing
