Blended: UV_B

Layered: UV_B

Layered_Sat: UV_A

The second albedo map with a roughness mask in the alpha channel.

This is blended in by Red Vertex Colour on Layer modes.

This is blended in by Vertex Alpha on the Blended mode.

Blended: UV_C

Layered: UV_D

LayeredSat: UV_C & UV_D

With Blend Mode Legacy_Layered or Legacy_Blended

• This is a linear BC5 map with two overlay patterns.
• The first in the r channel and the second in the g channel.
• The two are blended by blue vertex colour

With Blend Mode Legacy_Sat

• This is a linear rgba BC7 map.
• There is a multiplication map in rgb, and an overlay pattern in alpha.
• There are seperate UV options for the RGB (UV_D) and Alpha (UV_C) channels.
• The multiplication map is always used, and the pattern is blended in by blue vertex colour

Blended: UV_A

Layered & LayeredSat: Mix of UV_A and UV_C

This is a linear map with a mixmap or height map in the red channel, this is used to blend between albedo maps.

There is also also a specular mask in the green channel.

The map is sampled at the two sets of UV resolutions and blended with a 60% bias towards the higher scaling.

Layered: UV_C

LayeredSat: UV_B

The third albedo map with a roughness mask in the alpha channel. This is blended in by Green Vertex Colour.

This is not used on the Blended mode.

NormalMapA and NormalMapB are blended based on the calculated overall value from the weights set in Normal_Blends
