Exporting cal3d animation creates too many keyframes
 

I have a very sparse 40 frames long animation, with keyframes on frames 0, 20 and 40. When I export either CAF or XAF files, I get an animation with 41 keyframes, one for each frame. Shouldn't cal3d files keep my original keyframes?

Hi tgoulart,

What's going on here is that cal3d can store keys for position and rotation but does not currently have a way to directly store or use the tangent data needed to control the interpolation between keyframes. For this reason, animations are simplified to 1 keyframe per frame upon export. The exporter also has an option where you can adjust the sample rate (e.g. to 1 keyframe every 10 frames), though this isn't ideal for most animation.

Hi, Veleno.

Thanks, that was clarifying. Too bad that the tradeoff here is so extreme.

In the meantime, I managed to get the latest cal3d exporter to compile and modified it to export keyframes only, I'll just assume linear interpolation everywhere.
