A channel is a fluid property, for example velocity. The fluid's velocity channels is available as a series of vertex maps and can be used to visualize differences in the property's values. This way it is possible to achieve realistic shading effects. Please go to → "Mesh Channel Vertex Maps" to learn how to use channels with materials and shaders. For a workflow description how to use weight maps please visit → "Mesh Weight Vertex Maps".
