no that's for shaders. vertex animation is probably more similarily to skeletal. there is the point though that at least the skel morphing can be run on the gpu (and is by default), did you see shader references related to that? well i googled now a sec and the manual says: "Vertex animation is stored inside the .mesh file since it is tightly linked to the vertex structure of the mesh" http://ogre3d.org/docs/manual/manual_78.html#SEC338 > -p ~Toni > > Toni Alatalo wrote: >> On Feb 19, 2009, at 4:56 PM, Paul Fishwick wrote: >> >> >>> I have no access.
