This is a part of a current project. i applied a Solidify mod, and unwrapped, and got total silliness, all the faces are packed and converted to neat geometric shapes! https://s24.postimg.org/9hiaee96d/wtf_unwrap.jpg
i tried changing settings, eventually Smart UV Project gave a different result but then retrying Unwrap would not change the islands.
hmm. every other time i’ve unwrapped stull like that [like an engine, lots of indy components, it usually does each piece to varying degrees of correctness, i’ve never had this packed geometric stuff before.
Thanks Richard. i used Smart UV, got about what i needed. i just find it odd that the UV procedure just flat-out refused to work the way it always seems to have been happy to before. oh well, quirk of the tool or my model attributes i guess.
cheers
EDIT - damn, didn’t spot you’d added the file, many thanks for that, far better than my effort
