Hi, Zoo. I'm missing something here, how to make the cars point to the rail. I made a moebius object, and did two ring cuts - one for the path, one for the rail. Using Hiroto's polygon2Spline script, made those cuts into splines. The car tracks, tangent to the path spline, but I can't get it to bank to the rail spline. There must be some magic words I'm missing.
Thanks. Here's a quick and simple version. I made the moebius by sweeping a rectangle around a circle, with a 90 degree twist. Deleted the end polygons and bridged. It was surprising to me how well ring cut and loop select worked, as if the end patch was not there. Splines were made with the ring cuts using the Polygon2Spline script.It sounds like you have the car tracking fine but it's not banking to the second "rail" spline.
Can you upload a simplified version so we can check it out.
Yes, thanks! That is what I did. The bridge tool seems to clean up the end geometry pretty well.Yep, looks like I did not read the question correctly.
* If this does relate to Möbius strips:
* In this case: the rail needed for a Möbius strip is just the edges of the original strip when rotated by 90°. However, this assumes that the Möbius strip is a path tweaked by 90°.
* As has been mentioned in the old thread Frank B has been referring to, the mesh geometry at position 0 (start / end) needs tidying up as a rotated sweep on a closed spline results in a bit of a mess.
* ZooHead´s suggestion for an upload of a simplified version would be constructive.

Thanks. I tried making a second moebius, sweeping a larger square, doing a ring cut in the center and making the rail from that, but the car still seems to flip. There must be a step that I am missing.Like this should work.
