Questions tagged [height-map]

A heightmap is a raster image. Each pixel of the map stores values, such as surface elevation data. Blender uses height maps in materials through image textures as a way of faking (bump map) or producing (displacement) displacement using the material, along with other uses. Use this tag for questions about the use of heightmaps in Blender.
