There are a couple ways users can add custom channels to an item for the purposes of animating. Users can use the menu bar command under "Animate > Channels > Add User Channel", or users may also click the button in the 'Modifiers' subtab of the Animate interface tabs default toolbox. Additionally, modo provides options to add user channels in the 'Channels' viewport, both in the viewport itself (as an option) and and from within the context menu. Invoking the 'Add User Channel' command pops open the 'Create User Channel' dialog. These are additional channels that can be added to items, often used to add settings or controls to assemblies\rigs and\or to drive multiple other channels from a single channel via channel linking. Select the item you wish to add the channel to before entering the dialog box.
Channel Name: Defines a name that will be used to identify the new channel.
Type:Choose the 'Type' of channel you wish to create from several options
Float- Channel produces a floating point value e.g. generally a decimal and typically between 0 & 1
Distance- Channel produces a distance output value.
Angle- Channel produces an angle output value
Percent- Channel produces a percentage value e.g. 0% - 100%
Integer- Channel produces a whole number value (not a fraction) e.g. 1,2,3,4,5...
Boolean- Channel produces only a 'True' or 'False' type value
Mode: By default a single channel will be created with the given name, but multiple channels can also be created by using the options of the Mode popup, they are as follows:
Scalar- Creates a single channel, e.g. MyChannel
Vector XY- creates two channels; e.g. MyChannel.X and MyChannel.Y
Vector XYZ- creates 3 channels; e.g. MyChannel.X, MyChannel.Y and MyChannel.Z
Vector RGB- creates 3 channels; e.g. MyChannel.R, MyChannel.G and MyChannel.B
Vector RGBA- creates 4 channels; e.g. MyChannel.R, MyChannel.G, MyChannel.B and MyChannel.A
Use Minimum Value: Allows the user to specify and define a minimum value
Use Maximum Value: Allows the user to specify and define a maximum value
Default Value: Allows the user to specify the default value of the channel.
