I have a problem with unrolling tube sections of my tube, which is built along a closed line consisting of several straight lines. The problem is based in the built of each tube section. The are only built up to the cross section/end of its line. The missing piece to get an elliptical/closed crossing is added as an separate surface. Like this the unrolling is unnecessarily complex.
I never experienced this in V4. Are there any controls to influence the corners built?.
