Everything is rigged to the same skeleton, lower bodies use the monster skeletons instead (the hybrids are effectively permanently mounted on their lower body). Animations are slightly modified in some places, but mostly I just used what was already in game. If you equip boots on a halfspider it will be equipped, you'll get the bonus, but no 3d graphics will appear.
It's not perfect. Far from it. But it works well enough considering I'm the only one doing 3d stuff at the moment.
Thanks for your answer. It actually looks pretty impressive, considering you're just one guy doing all the work.
Did you reuse the meshes they had in FE as well or did you create your own? I suppose you had to do some stitching of the upper and lower body meshes for the hybrids to make sure they look correct?
Sorry for the questions. I'm still not really getting how you managed to get hybrids into the game. Short of creating and rigging your own models, even if you're reusing the ones in FE and even if the game supports having multiple skeletons (for upper and lower body animation) you'll need to somehow export and stitch the meshes together so they look consistent.
