To get a better collision fit, the best solution is often to have the 
artist who authors the mesh, also author the collision approximation, 
usually using some combination of spheres, boxes, and capsules (because 
those are the most robust). Thus, in your art tool, you'd have to allow 
artists to build un-textured primitives that you could extract in a 
format that your code can understand and re-create in ODE.
