Channel Groups (Import Preferences)

 
 
 

In the Project Preferences window, you can define new groups in the Import tab. A number of default channel groups and predefined assignments are provided. Groups can be added, renamed, removed, and channel mapping can be updated.

The predefined groups are:

Group Mapping
Alpha A to A
Colors RGB to RGB
Colors + Alpha RGBA to RGBA
Depth Z to R
Surface Normals NX, NY and NZ to R, G and B
Velocity velX and velY to R and G
Note

The groups map to a subset of the channels available from the Splutter Fish plugin used by Autodesk 3ds Max: Velocity, Depth, and Surface Normal.

The selected group, Velocity, is predefined by Composite. It defines a mapping of channels named velX and velY to output channel R and G respectively. No channels are mapped to B and A.

Under From File To Output are four fields labeled R, G, B, and A. Each contains all the channels available in the EXR file.

Channel Description
R Red Intensity
G Green Intensity
A Alpha Opacity
U Equivalent to X-axis in a 2D plane
V Equivalent to Y-axis in a 2D plane
Z Z-axis or depth in a 3D plane
NX X-axis Normals
NY Y-axis Normals
NZ Z-axis Normals
materialID A surfaces material ID is the value that determines which sub-material the surface will use when you apply a Multi/Sub-Object to a material to the object to which the material belongs.
objectID The value that determines which object will be used when you apply it to the object.
velX X-axis Motion Vector
velY Y-axis Motion Vector
None No channels selected
