How to Make the Texture

in the last post

 

The following uses Photoshop CS6 but other paint programs should work.

 

Two things you need first:

 

1. A UV map of the mesh:

 

2. A AO map, (Ambient Occlusion) you Bake this from mesh:

 

 

I start with the UV map and the AO map open in PS. Duplicate the AO map layer to the UV map so you have two layers, close the AO map.

 

 

 

 

Note that the layer is named Background and locked.

 



Next change the Background Layer to a Channel, this unlocks it.

 

 

Now add one more Layer and move it to the bottom.

 

I have renamed the layers and made the AO one active and visible and added an Alpha Channel.

 

Next you need to get the AO map into the Blue Channel. Start with the above and go to Channels.

 

Now you fill with black, it should look like this:

 

Do the same with Green Channel.

 

Here you see the AO map is now in the Blue Channel but it should have a white background, Color Select black and fill with white.
