Adding Geo-Channels to Objects
You can add Geo-Channels to your objects to define arbitrarily named geometry specific data such as ambient occlusion, and curvature in your material creation workflow. Since geo-channels are geometry-agnostic, you can use the same material across a variety of objects while ensuring the material looks realistic for the specific object. Geo-Channels must be added to your object in order for Geo-Channel nodes and layers to function. See Geo-Channel Node for more information.
Tip: You can also export baked data from Bake Point nodes directly into Geo-Channels, to act as an intermediate caching point for complex Node Graph setups. See the Bake Point Node and Working with Nodes for more information.

Adding Geo-Channels to your Object
|1.||Open the Objects palette.|
|2.||Select your object from the list of objects in the Objects palette.|
|3.||Scroll down to Geo-Channel Properties.|
|4.||Click the button next to Channels to add a new geo-channel.|
A new geo-channel appears in the list of geo-channels.
|5.||Click a geo-channel to enter a new name.|
|6.||Click the next to the specified geo-channel to import an image set for that geo-channel.|
Note: The imageset bit-depth for geo-channels automatically converts to the bit depth of the imported texture.
Importing Modo Render Bake Results as a Geo-Channel
If you don't have any rendered maps to use as Geo-Channels, to use Mari's built-in Modo renderer. The built-in Modo renderer allows you to bake textures for your objects within Mari.
To import the baked results back into Mari as a geo-channel:
|1.||Open the Modo Render palette.|
|2.||Select the Bake tab.|
|3.||Select a preset from Bake Preset.|
A preview of the bake is generated.
|4.||Enable Bake As > Geo-Channel option.|
This imports the baked result back into Mari as a Geo-Channel.
Warning: This destructively overwrites the contents of a Geo-Channel with the same name, or automatically creates a new Geo-Channel if one of the same name doesn't exist.
