UV mapping with Wings3D

[micheus]

ps. When I compare others UV car texture it seems Normal unwrapping is the most popular. I wonder how they do it, so the texts are not stretched.

yes, it seems to work better and you need to create many islands and then Stitch (weld) them in the UV editor.
There is a article for 3d max which content can be adapted to be used with Wings3d: Ford Escort – 3DS max car texturing tutorial

Sometimes I use Image... primitive to create a checker pattern that works better for some situation - as now I was unwrapping a bottle. It makes easy to see the proportions and avoid relevant distortions.
