Hi all,
We are in the process of upgrading the animated horse models in our game.
The original models were developed in 3dStudioMax and I was able to fairly
easily use the skeletal animation data and bone hierarchy from there in our
custom viewer.
The new models and animation have been created in SoftImage 4.2 and now
I'm battling.
The quickest way I could think of to convert the animation from dotXSI into
a format I can use seemed to be to import the XSI models into 3dStudioMax
and re-export. I have been able to import some simple dotXSI models into
3ds max 4, but with limited success. I had to filter out large parts of the
dotXSI for the full horse model before I could get the skeletal structure
into 3ds, but the result in 3ds bears very little resemblance to a horse
skeleton.
My question is, is there a better way to do this , especially if I can get
all the information as I need it straight from XSI ?????
I basically need the usual hierarchy of joints attached to one or more
roots. Then for a number of keyframe samples I need either Euler, Axis-Angle
or Quaternion rotations for the joints, and transforms for the root(s). I
have searched the web unsuccessfully for ways to programmatically convert
the FCurve data (with the left tan X etc.) to keyframed rotations.
I have the Softimage FTK 3.6.2 but that doesn't really help. Does anyone
know of any other web pages , documentation or examples I should be
reading?
Any help will be greatly appreciated.
Kevin
