is it possible for example: To have a grunt and import some other entites to merge whit him? (silly example: a grunt whit some clothes on he's hand) is it makeable?
AFAIK, you cannot import more than one mesh at a time. I tried that a lot, especially while making a custom door entity, but no luck.
Devs said that tools are in instant development. Maybe new versions could include some new features, but I doubt we will have updated tools.
Well you could do it whith a 3D create programm, like 3Ds max, blender or Maya :p
