I think dont need redo all uvmap. Just resize old cockpit textures to 2048x2048,and paste to them new better textures.i can try this.
You will need to reposition the surfaces on the new textures. They're completely different layout.
I don't think Devrim will send the PSD files until Ricardo gives the ok. I can find out which parts were his own work, and which were from existing DCS, then we can just re-make those parts. The textures are all stamped with copyright to Ricardo and Devrim, so if ED still owned parts of them, they couldn't claim copyright on them.
But it's a step forward, and something to stay positive about.
