Well to put it out there I’m interested as well in using UE4 to make animated shorts and there are some interesting applications and products that would be well suited for this purpose. As a suggestion what would be nice would be a forum section, like the Architectural Visualization where such ideas can be discuses but an app/product that would be well suited for character development would be Daz Studio from Daz 3D.
Like most applications though there are issues to work around and a learning curve to get through but is worth the effort as a starting point.
