yeah, when i initially had 3d canvas i had the exact same problem, i made a house and animated the door swinging movements but when i loaded it and looped it on dark basic something whent wrong

there was some info. about that on the 3d canvas site (www.amabilis.com). Well, i guess if the site does not sort you out then you'll have to either get 3dsmax (if you can afford it) or seek another 3d modelling program.
