I need help with this car mesh im trying to make...

i downloaded this mesh from an unrelated site but it has over 107 groups and i dont know how to link groups together so it is easier for me to link joints with the verticies in the group

plus how do u manipulate the joint assignment so it fits the vehicle i am making out stuffing it up????

If this mesh has 107 separated mesh groups then it must have an *enormous* amount of vertices and faces!
Remember that on several sites you can find free meshes, but they are intended to be used for static raytracing, NOT in a dynamic environment like this game.

If you can reduce the mesh to about 5000 vertices, then refer to this tutorial for the joint assignments and other car-related hints.
