Texturing: Essential Knowledge

This section explains concepts fundamental to a successful texturing experience.

Correspondence of uv-sets to texture layers

There is a 1:1 correspondence between uv-sets (texture coordinates sets) and texture layers (maps):

uv-set Texture Layer
0 colormap
1 bumpmap
2 dirtmap
3 specularmap
4 opacitymap
5 normalmap
For more details about the texture layers see Material Shape Attributes. and material.map: Texture Layers.

Defaults if no uv-set present

For rendering and export, each defined texture layer needs to be matched with a uv-set. If a texture layer has a texture assigned, but the corresponding uv-set is not defined, the texture coordinates from uv-set 0 are used. If uv-set 0 is undefined, the texture layer is ignored.

Supported Image Formats

A large number of image formats are supported, the most popular ones are:

Extension Description
bmp Microsoft's classic bitmap format.
gif The legendary Graphics Interchange Format.
