Hi,
I'm working on BVH files and retargeting on model. My tests say that BVHReader
supports the MotionBuilder BVH only, so the 3D model needs to have the skeleton
bones with Y up convention.
I have some models from MAXIMO that come in an old 3D model set that works fine
(exported by MotionBuilder 7.5). Because I need to apply BVHs to a different
model, I've tried to copy the original working skeleton to a my model.
I'm using C4D R18 (exporting in FBX 2010 because is the only one that works
well with textures export too) to do that and basically works.
But there is a problem. In the first video ("ok") we can see the original
model: he falls on your knees correctly using as origin point one at foots
level.

In the second video ("wrong") we can see the new model with the original
skeleton exported via C4D: it falls on your knees in a wrong way using as a
point of origin one at waist level.

In C4D the main axis of 3D model is EVER at foots level, there are no changes
about axis position. Simply, if I'm import in the C4D the MIXAMO original model
and I export the SAME model without any modification, the incorrect behavior
come up! We have a similar behaviour using Blender also.
Someone had a similar experience using BVHs?
Thank you!
Cheers,
Dario
