I'm working on physics, I saw his editor too, and I am adding the loader for the XML file to the WGE. I know convex hulls are inefficient, but I was just trying get physics up and running quickly.
The funny thing is, your post is essentially my todo list

I really don't have much physics experience, so that'd be great if you could help with the physics stuff. As long as its okay with pjcast :wink:
On a side note, I've been working on getting terrain to load into OgreNewt as a ConvexHull, I'm almost there, but, I'm having trouble with getting indices for the terrain.
I would love to see the PhysicalActor class, is it tied into the Actor class only, or can you use it for other types of physics objects?
