Hello,
It is hard to figure out the correct scale for the meshes because neither Blender nor ogre use "real units"
I think we need to scale the "cube.mesh" to 2meters and use it a a meter-stick
An average person is 6" ~ 1.80meter. So Any character should be pretty easy to compare and scale
I added new animation to the classic robot. Again scale may be off.
