I’ve been using Poser to make some 30 second animations for my own use. I’ve done a lot of reading about how BVH files are optimized in uploading to SL, and how to prepare them. Even so, I have had some limb drift in some of my animations so I’ve had to break splines more than once to stop it from happening. My problem is the animations move just a small amount (flinch) when playing from one broken spine to the next broken spline when playing in SL. It’s not much of a move. You have to be looking up close to see it, but the limb does flinch because of these spline breaks I have to make to prevent limbs drifting. I’ve done the usual such as: setting up frame 1 at SL default T settings, starting my animation on frame 2, moving all joints at least 1 degree, lowering frame rate to 15 frames per second. But, limbs still drift and I have to use spline breaks to stop it. Any suggestions on how to stop limb drift without spline breaks? Or if not, is there a way to smooth out the playback flinching caused by the spline breaks? I see the buttons listed below next to the Spline Break Button: Spline Section Linear Section Constant Section I don’t know what they do. Should I be using one of them instead of Spline Break?
