We have been trying to find a way of making importing assets a breeze, and we have improved this for skyline.
In the next auto update, you should be able to import FBX Files that work for static meshes and animated characters alike.
We have successfully imported many characters with FBX and ended up with a full accurate animation track.
Above are 2 characters that were both converted from .fbx to .mesh, and .skeleton, they both have a full single track of animation, which leads to the next feature. A tool for splitting animations into new animation tracks is being developed, so you will not have to touch the modelling application to get characters in.
We do have planned to add a mesh normal unifying tool as some meshes after import have inversed normals or selective inversed normals.
This is a coming soon feature though and probably will not be included in the next release.
And Finally to top it all of. We also have a working mesh editor again, so you can reposition, rotate and scale your meshes.
Except characters can now be scaled up or down including their skeleton without loss of animation or skeleton structure.
EDIT - To get the FBX displaying in the asset manager, activate the "Misc Mesh" in the filters.
