A new revision (2008-05-28) of the Blender to BVH exporter is available. Here are the noteworthy changes:
- Added GPL2 as licensing option.
- Added hand and foot control bones (scale 1.5 to enable).
- Bone adjustments to make Auto-IK work better.
- Auto-IK enabled by default.
- Minor skeleton tweaks in the knees.
A note about Auto-IK: for this revision, Auto-IK is enabled already, to make it easier for beginners to pose the armature. Just grab and pull on the arms or legs (but not the hands or feet; those won’t work), and the limb will move around. If you don’t want Auto-IK, click off the “Auto IK” button in the panel on the right (about 1/3 of the way down the screen).
A note about the hand and foot control bones: by default, they have no effect. But if you scale them up to scale 1.5 (select the bone, press S, type 1.5, press enter), the corresponding limb will try to reach for the control bone, using IK. You can use this to keep the feet planted on the ground, for example. If you don’t want the control bones cluttering things up, you can hide them by selecting them and pressing H; get them back with Alt-H.
By the way, a tip about using IK targets (like the control bones): it works best if the limb is already (without IK) in a pose similar to how you want it. So, IK just gives it that extra “snap” to keep it in place. If you only use IK without posing first, the limb might bend the wrong way and you’ll have to see a doctor.
Enjoy.
P.S. This doesn’t mean I’m maintaining it… :P
