Maybe someone can tell me if there is a Sod plugin for "Ultimate Unwrap 3d" 2.15 ? I have one but it is made for v2.29
Just go to the UU3d homepage and download the latest version of the program and its plugin. If you have a legit version then just email Brad Bolthouse (the creator of UU3d) if you can't get it registered and he should (as he did with me) send you the correct file for it to be the registered version. Failing that just do a google search for that exact version.
