So, What I was wanting to see is more of a secondary layer to put a image into ...
You can think of the second "layer", I specifically would NOT want "on the fly AO", but rather a defined AO image that Icreated and imported.
Also You can think of this idea of adding drips from window ledges, rust stains, edge grunge, graffiti... Anything you can imagine...
So one layer would be tiled.... so i can repeat it over and over to use a tillable material, then i could add a Grunge/AO map that is defined in a 0-1 UVspace... to add a extra detail. How you can do this now with duplicate geometry.. and i feel it will also be that way going forward..
I just figured before a release is done, we should try to add as many features now and fix them before adding them later/never >_>
