From what I’ve read, it seems Blender allows for mostly getting it all done… but there was something about an extra bone being exported, and something about regular bones instead of deform bones (but I don’t know what those are, so that doesn’t help!)… but they’re saying that the newest Blender (not out yet?) should -mostly-, almost completely, export skels/anims that will be usable in UE4… but not until 4.2 comes out.
So, it seems we soon will be able to use Blender for all of it, just not today. … I’m sure someone can explain the current hiccups, or you can search the forms for info (I read something about it just today in the General Discusion area).
My plan is to use Blender… but since I’m a good ways away from worrying about it, I’ve not done due diligence to learn what’s all not quite right in the process… I’m still working on getting switching from 3rd to 1st person with stock anims and holding guns… lol.
