Good find Robo..
I never thought about that, and the fact that it's not needed anyways (I didn't think about the file size and just thought it looked cool
).
I've reduced the size from 3.20mb to 2.34mb by getting rid of this layer. Unfortunately with this skin, the rivets I used was from that layer, so to fix this on all 12 planes will take some time.
**Edit, PS.. I don't use Photoshop.. I use Paintshop Pro.
