Wurm Online uses dotXSI files for models and animations, but the support in the client isn't complete enough yet, so now we're looking for help.
The reason I haven't finished this is both that it's pretty complicated stuff to get right, and that it's so incredibly boring (I'm really selling this one, aren't I?
The job would include develop joXSI further to support loading animations from separate clips, implementing various minor features for the model loader, like the ability to get the world position of an animated mesh to be able to emit particles from there, or the ability to plug one model somewhere in the hierarchy of another model (a guy holding a sword in his hand).
Further work, if all works out, includes possibly writing a nice glsl shader for the skinning, perhaps some basic inverse kinematics, and advanced material support.
We can't afford to pay much, but we do have some money to spend. You'll also receive full credits in the wurm online credits, of course, and the posibility of more work in the future.
