View Full Version : Automatic Unrwap problem

This is starting to get on my wick. I have a 3d model which is already beautifully UV mapped. Max's auto-unwrapping is totally unsuitable for this model, it makes a complete arse of it. Now the Render To Texture dialog provides an option to use an existing mapping channel, right? Great!! I'll just use that then. Off we go with a nice GI solution to bake in my lighting. Wait a few minutes, well it's high quality so that's ok. Now we'll just reapply the texture and.. WAIT A MINUTE.. it hasn't used the existing mapping channel at all. It's used some @#!*-eyed messed-up mapping that's neither the existing mapping nor the auto-unwrapping it wants to do. So I end up with a texture where things have been rendered over other things and doesn't vaguely fit the object with the current UV mapping, nor with any of the auto unwrapping variations.

Lighting needs a UV layout that has no overlaps and where all the UVs are contained within the 0-1 UV space. If your existing UV layout doesn't have this, the bake will not look good.

Are you sure that RTT is set to the UV channel you want to use?
