I wrote small program, which fixing (ParentItem and -3.14 problem) exported C4D scene from boujou 5.
It's really simple to use:
1. Open program, click "Otwórz" button (Open), chose your exported scene, which you want fix. After succesfull file loading, you should see path to your file next to "Wykonaj" button.
2. Click "Wykonaj" button (Make). After that, boujou 4D will create new file named "Tracking.c4d" - all done, it's fixed file.
boujou 4D is available under this link: http://www.grafikuj.pl/boujou-4d/ (click "Pobierz" (Download) at the bottom of article).
