$multipass

$multipass is a VMT command which forces a material to be rendered in separate rendering 'passes'. This can fix issues with translucent materials, although rendering will be more expensive. This command is required to allow DX6 + DX7 users to see cubemaps, and it has also been used on breakable glass materials.
