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-setTexture Layer

0

colormap

1

bumpmap

2

dirtmap

3

specularmap

4

opacitymap

5

normalmap

6

emissivemap

7

occlusionmap

8

roughnessmap

9

metallicmap

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:

ExtensionDescription

bmp

Microsoft's classic bitmap format.

gif

The legendary Graphics Interchange Format.

jpg / jpeg

JPEG compressed images.

png

The popular Portable Network Graphics format.

tif / tiff

The flexible Tagged Image File Format.
