| Post subject: | Collar rotations off in Poser/Studio BVH |
I'm trying to sort out the work flow to get the captures into Poser. I'm not totally sure I'm doing the "Import Target Character" part right. When I load the saved BVH into Poser I get incorrect Collar and Shoulder rotations. The Collars are bent all the way up and the shoulders are way down. I imported a BVH single frame saved from Poser with the figure in T-Pose. Then Imported that into iPi Studio. Is that right or did I miss something here? In iPi Studio the imported character seems to line up fine but the export to Poser is going wrong. Any Ideas? |

It is well known bug in Poser. For more info see http://ipisoft.com/en/wiki/index.php?title=Animation_export_and_motion_transfer#Poser |

That's good to know but my problem isn't with wrist (hand) rotation. It's Clavicle (Collar) rotation, but this has given me a clue as to what's going on. Poser uses the next body part in the hierarchy as the end point for the previous one. It seems that's not how BVH works or at least not how it's being handled on import. I've messed around with the Rig for P8's Alyson and come up with a solution putting the end point of the bone where it expects it to be instead of where it is. Since Poser ignores this except for the last part in a chain it should fix the problem. This requires a special rig in poser but it's only required for the BVH import. Once the animation is saved as a Pose in Poser it won't matter as PZ2 files only contain rotations for each part. Off to verify this all works as expected... |
