Vertex Painting
Anvil keeps vertex painting close to Blender’s built-in workflow.
Anvil taking Right Mouse for free look overrides the default hotkey to open the context menu.
Instead, to open the colour picker, use press C.
For vertex colors to affect an Anvil material, enable Vertex Colors on that material or in the default material settings before the material is created.
When you enter Vertex Paint or Sculpt mode in the Level Design workspace, Anvil enables Blender’s Face Orientation overlay automatically to reveal faces backface culled faces (which will block painting and may otherwise be confusing). Anvil makes the front-face orientation overlay transparent.
