IMPORTANT: Do not re-color your model without permission of your artist!!
You can now use hotkeys to load ArtMesh screen/multiply color presets.
To do that, prepare your model with the ArtMesh colors you want to register, then create a new hotkey of type "ArtMesh Color Preset". Use the "Record Settings" button on the hotkey UI to record the current settings. This hotkey can then be used to load/unload that screen/multiply color preset.
You can also create a hotkey of that type with empty settings to create a hotkey that removes the currently loaded color preset for that model.
