MeInOhio, 'Does that mean if I have three windows and the one in the middle faces front and the other two are at 45 degree angles to the middle one, that I can map the front window and export it and then import it for the other two windows and that the map will apply correctly for the angled windows?' That's exactly what it means. I've just finished a bay window where the left/right windows are set at a 45-degree angle. Plus each side had roller-blinds, crossbars, venetian-blinds, etc. I just mapped each of the pieces in the center, exported the uvs and re-imported them for the angled ones. It's one of iv mapper's best tricks. Otherwise, mapping angled abjects is a nightmare. Plus, any figure where you have to map multiple pieces, each one the same, just do the same trick. It's a big time-saver. Ajax, Your way sounds wonderful.... if I could understand it. LOL. What do you mean by 'The axis of the cylinder should be at the centre of the full circle of which your arch is an arc' Do you mean using the offset values? And which axis? The Z-axis, I'd assume. To complicate matters, my arch is squashed, so it's not even a true circle. Nerd, Your idea would have been great, and I tried it. I straightened the arch in Anim8or, did a cyl cap/X-axis and exported the uvs, then re-imported them, but the vertices were all skewed, and the result was horrible. I then tried lining up the vertices (an experience I wouldn't care to repeat often), but I can't get them right. I think I need to rebuild the arch at this point. I'm going to try a non-squashed tube, make a straightened version and get the uvs from it, then squash the arch by scaling it in poser. Then re-attach it to the rest of the arch, then stick it back in the figure. Or maybe I'll just forget the arch.... Thanks all mac
