hmm. Im using Blender. Actually I only have a Problem with a skeletal mesh where a frame seems to be missing. Epic is in talk with the Blender Cracks out there to fix it. So focus on other things for now (Im building my City at the moment instead of animating) . I bet u have tons of things to do besides the animation stuff. Get back when Epic releases a fix… I bet they will come up with a super duper hyper deluxe mega FBX brainwashed awesomeness pipeline. or something like that… dont give up.
Oh. And 3ds . Good thing though. but you MUSTNT use it commercially… I`m also in the Student section. The Licenses are kind of “Watermarked” …
Stick to blender if you dont have money (or want to spend some). It`s as simple as that
