Viewing Muscles (UE)
The Muscles tab displays all of the muscles in the Character Control File.
Currently, muscle editing is not possible in Unreal. To edit muscles in Maya, see Editing Muscles. And for an essential guide, see the Muscles article in SGX Concepts.
Muscle activations update in real time during animation streaming from SGX Director. See Streaming Animation.

Muscle poses can be manually activated by dragging the sliders.

Additionally, you can visualize the movement of a given muscle – from the relaxed state to its current value and back – by clicking the ‘play’ button on the right side of the activation slider.

The resulting animation illustrates the dynamic characteristics of the muscle in isolation. (However, note that since muscles are not currently editable in Unreal, the dynamic parameters must be edited in Maya.)
