As expected, I'm completely green in 3d modeling, and I quickly ran into a weird issue within Blender v2.73. I've modeled a simple solar panel divided into two parts- the frame and the silicon surface. The surface's UV layout is perfect, but whenever and in whatever way I try to unwrap the frame, it always comes out distorted. I tried different seam patterns- non of which worked, so in a final attempt to simplify the shapes as much as possible, I marked every single edge as a seam. No change. Most shapes are still distorted, even though there is not one distorted face in the frame mesh. I did a lot of google-ing and I found some alleged solutions, but non of them worked either: -Remove doubles from mesh- A good practice anyway, from what I've read, but no effect in this scenario. -CTRL+A- Apply location, rotation, scale, while in object mode in the 3d view window - No effect -CTRL+A- Average islands scale, while in the uv editor window - No effect -CTRL+V- Minimize stretch, while in the uv editor window - No effect I'm really keen on modeling new parts for this game, and I have some interesting ideas, but snags like this one can kill my enthusiasm quite quickly, so I'm borderline desperate to find a solution to my problem. .blend file
