The Preserve UVs HUD is a head up display for Maya’s viewport that display the current state of the preserve UVs parameter so that you can easily track if it’s on or off. A hotkey for toggling the preserve UVs state is also provided with the tool.
You can assign a hotkey to the Preserve UVs HUD inside the Maya hotkey editor.
The hotkey entry can be found in the Custom Scripts tab under GENtools → View → Preserve UVs HUD.
You can enable the Preserve UVs HUD to load automatically on Maya’s startup from the GENtools Startup Settings.
