A little explanation about variant

(TL;DR) I hear you and I'll make a Miranda variant! Diana or Tali model don't exist in Blender so I can't, as for Jack, you need to read below. (I'm surprised about Jack popularity here! o_o)First, thanks for your comment! I see you loved the animation, I wasn't sure ^^'Okay so let's explain a bit about character variant.

We can move a model with a Rig and Bones. But most of the time, Rig and Bones' names is never really the same. So if I want to make a variant, I need to redo the animation from scratch.

But with Rigid3D model, Rig & bones are the same. That's why I can "copy/paste" animation for Liara, Ashley, Miranda, and I'm quite sure I can do it for Ada, Claire and Jill too.

After copy/paste, the animation isn't perfectly match tho, I need to tweak some keyframe, positions,  hair, physics (because model doesn't have the same bodyshape) .. but the core of the animation is here, so I gain a LOT OF time.That's why, sometimes, I can do variant (All rigid3D models, and probably a lot of Niodreth Models), but can't for everyone like Jack because it's an Icedev model and he doesn't use the same rig at all.Hope Its helps for understanding variant =)
