And it seems motion path is doing it right. May be the pointOnCurveInfo is not calculating it right for extreme angles. Would be interesting to look into it.maulik13https://www.blogger.com/profile/01516378468606581144noreply@blogger.comtag:blogger.com,1999:blog-3269636004740581152.post-17184762183309304382011-12-14T15:23:39.956+01:002011-12-14T15:23:39.956+01:00Hi Maulik, I´ve faced that problem while ago..

In the end I´ve rebuilt it using motionpaths.<br /><br />Best regards,renato polimenohttps://www.blogger.com/profile/17689287969782033324noreply@blogger.com
