`metallic`readonly	`number`
`metallicMap`readonly	`ChannelSource \| null`
`roughness`readonly	`number`
`roughnessMap`readonly	`ChannelSource \| null`

`transmission`readonly	`number`
`doubleSided`readonly	`boolean`
`uvMap`readonly	`string \| null`	The UV map the maps read, by name, or null for the render map.
`uvTransform`readonly	`number[] \| null`	A 3x3 affine transform of that map, column-major, in Blender's UV space, or null.
