PBR setup

Part 1

texture.004 is the normal and bump. The normal gives an angle and the bump the displacement. The bump is in the Alpha channel and is in gray scale only.

 

 

Set to Normal in Blinder.

 

 

The RGB part is the same normal map we have been making. The Alpha channel has a new use, how high or low it should look, white is max. up and black is max. down.

To do this turn on the Alpha so it is visible and active. In the above it is not visible or active, the RGB is, you need all visible and only Alpha active, then you can paint over your normal line.

 

Here you can see only one panel line has a black line in the Alpha channel.

 

This also gives you parallax that make the flat mesh look like it had deep indent.
