First of all, I have to say that it is purely a coincidence that I have done two posts in a row with a picture of a skull.  I really don't have a thing for skulls I promise.  The one that I used in this demo just happened to be a good test case for the tool.  

I'll really try to resist including any skulls in my post next week :) 

Aside from working on this new UV tool I'm preparing for my sessions at MIGS next week.  MIGS = Montreal International Game Summit.  If you live in Quebec, or if you happen to be traveling there for MIGS, stop by and check out my sessions...

-and-


So, this new UV tool that I'm showing in the following movie is based on something I did a long, long, long time ago for Sega in SF.  It became a bonusTool called Automatic Wrap Map. 

 

You've probably never tried it but if you did you probably found it completely unintuitive and somewhat limited.  So this new tools is based on it in general, but it is much improved and hopefully much more useful.  It's called Auto Unwrap UVs Tool

It can be used to interactively and automatically create UVs for lots of different types of forms.  Check out the movie below to see how it works.  If you're interested, or as we sometimes say in Texas "inersted", I've posted a beta version of the script that you can try out (see link at the bottom of the page)

 

 

Here is the script is you'd like to give it a whirl ->  bt_autoUnwrapUVTool_beta2

It's in a late beta form, which means it works pretty well for me and I think I've ironed out most of the glitches, but it hasn't been thoroughly tested by others.  Any feedback would be great.  Just open the script in the Script Editor, then select it and drag it onto a shelf. The resulting shelf button should open the UI.


 

 **UPDATE**  The update to this tool is now available -> Unwrap UVs Tool Part 2

PixelDroid - I think your shell is too big and too complex for the unfold algorithm to handle. Try breaking this up into separate shells... at least one for the head and another for the shoulder area. The head shell would have a border around the neck. Also try starting the seam higher up on the forehead. Also it looks like you may have an interior for the mouth? If that is the case you will need to separate that out as another shell as well.

This looks very useful, but I'm having trouble getting it to work.
I followed your demo using a different head mesh, but I'm having problems w/symmetry in the unwrap - the UVs are not being mirrored correctly.
Any idea what I'm doing wrong?
Thanks.
