Don't know if anyone is still alive here, but over the past few days, I've been playing with Blender a bit for the sake of creating content for Unreal Engine (some personal projects). And after some minor back-and-forth with settings for import/exports, it obviously got me thinking about ye olde TM modding scene. Some might remember me, I don't know.
Anyway, the short thing is, I recalled that someone had managed to import characters into Blender, like, the Starmaker variants. I know that other assets (props, costumes, etc) were brought in, and saw too that Lefty2000 had brought animations into Blender.
Now, the version of Blender that supports the actual TM import/export scripts is not the latest one. Not even close. But just the whole... thing made me realise that it wouldn't be too hard to import some of this content into Unreal Engine. Totally f'ed as far as legality and usage goes beyond a personal thing, but it could be done.
Sure, the world has moved onto better ways of doing things (to the point one might say ditch the whole thing or try to make new content in the same style but with animations/techniques that are more current though inspired by the original) but it was an interesting thought experiment.
That said, if you were able to do all that, you might find it easier to just straight-up use Unreal for animation in its native sense, but it's still an interesting thought.
