This might help. http://sketchupdate.blogspot.com/2007/07/wrapping-image-around-cylinder.html There is also a new(ish) UV Tools ruby script in the Ruby forum that, if you set it to cylindrical, will wrap an image around a cylinder precisely once. There are posts here and on the Google Groups site that deal with such things...cycloramas. There are also a few posts dealing with complete skydomes, which will also work; if you need to look up a little more.

Thanks guys, I'll try these ideas out. I've loaded skin.rb just need to work out how to use it! It keeps joining to only one corner of the second face.. Nick
