About Reading Collision Meshes

This is a Cross post from Pipeline but no one answered my thread there so I Figured I’d see if you guys knew

Can any one explain how to do the collision mesh in blender? I have A plain I’m exporting as an egg and I added Property type string “Name:Collide” and “attribute :stuck_out_tongue:olyset keep descend” like it says in the roaming Ralph Demo. How ever this doesn’t seem to do the trick can anyone tell me what I’m doing wrong?

I looked at the chicken docs and this thread [Blender and collision geometry) and the left me kinda lost. Any help would be awesome.

Thanks Guys.
