exporting into SD - rotation flip bug

Postby spigigombos » Fri Jun 06, 2008 11:34 am

as mentioned in http://www.realflowforum.com/view_topic.php?id=1807

When I export objects simulated in RF4, when I load the animation into Lightwave, all rotational data is in Mod(360). In other words, all values are stores in a range between -180 and 180 degrees. If something should rotate to 181, it instead loops around to -179, resulting in what should be a constant slope on the graph editor to instead take a sawtooth pattern. This is normally all well and good, except when I try to use motion blur, in which the renderer, of course, registers these between-frame 360 degree spins, and blurs the objects practically out of existence.

I'm not a LW user so I can't confirm if this works. Try a different axis setup in the RF preferences to see if the output is the same. I've heard of axis and mirror problems, but not the one you speak of. Cheers!
