Hi David, I am currently working through your UVLayout tutorial (uv_layout_part_03). Another great tutorial btw. I did the UV's for the first leg and then tried to copy those across to the other legs but the software said 'No unflattened matching geometry found'. I them manually did the UV's for a second leg to see if they would copy across to the remaining 2 legs but it presented the same error message. Any suggestions greatly appreciated. Screengrab attached. Thanks, Jamie
