mighty_DG2Parallel_play.mel

// DG to Parallel toggle script v1.2
// Olivier Ladeuix
// http://www.olivier-ladeuix.com/blog/

// Function:
// - When hitting the DG2Parallel hotkey, the script toggles the evaluation from DG to parallel on playback then stops the playback and reverts back to DG when hitting the hotkey again.
// - For better understanding of the mode used, the evaluation state appears on the Head Up Display (HUD) in the viewport.

// Usage suggestion:
// - Allocate the runtime command to a hotkey
// - the Runtime command is : 
//    mighty_DG2Parallel();

// Suggested hotkey: shift + v 
// (v for regular playback toggle)
