Here is a channel filter. Here you can choose which type of channels to be displayed in the Channel Selector. You can sort them by functional groups.

Display All

lists all channels.

Display X-Form

lists all X-Form properties of the selected groups.

Display Specific

lists all specific properties of an object. Material is a specific attribute since it is only available in groups, plugins and materials. Also f-stop is a specific property of cameras.

Display Texture

lists only all texture properties of an object. If the object has no textures applied the list will stay empty.

Display Deformation

lists only all deformation channels if deformations are applied to your group. If the object has no deformations applied the list will stay empty.

Display Morph

lists only all morph channels if the object or model file uses any morph groups. If the object has no morphs applied the list will stay empty.

Display Constraint

lists only all channels that will be added to an object if you apply a constraint to it.

Display Socket

lists all plugin channels like Xpressionist Custom Channels or channels of particle plugins.

Note: When you select more than one object in the Object Selector only the channels that the selected objects have in common are displayed in the Channel Selector.
