Mapping Method for Multi-Material Object (iClone 3.1)

If you have a compound model in which each component model has its own material or texture, re-generating UV has basic rule as follows. We will take Box UV Setting/X/Tiling (U, V)=(1.00, 1.00) as the mapping method as an example.

(When you do material assignment or texture mapping to individual faces in SketchUp, it generates a compound model with several material settings.)

Single Model, Single Image as Texture

When you have a single model with its faces mapped by one single image, and you apply the UV setting as describe above, the result will be as the illustrations.

Partial parts of one image are mapped to
different faces.

UV Setting: Box
Align: X
Tiling (U, V): (1.00, 1.00)
The whole image will fit into each face.

Single Model, Multi Images as Textures

When you have a single model with its faces mapped by several images individually, and you apply the UV setting as describe above, the result will be as the illustrations.

Partial parts of two images are mapped to
different faces.

UV Setting: Box
Align: X
Tiling (U, V): (1.00, 1.00)
Each image will fit into corresponding face.

Compound Model, Multi Images as Textures

With the concept above, if you have a compound model with multiple textures, once you apply the UV settings, it will effect all the component individually with the setting, which is different from the traditional mapping method.

Partial parts of two images are mapped to
different faces of two components for the
compound model.

UV Setting: Box
Align: X
Tiling (U, V): (1.00, 1.00)
Each image will fit into corresponding faces of
the two components for the compound model.
