if i need to change material settings for the acc-file (when using only one material) i also use an text editor, but i am only a casual user so there might be better ways.
having more than one material is tricky (therefore i also almost never use it) because while it takes on all materials in the ac file i find that all triangles get assigned to only one material.
andrew, who made the 1936 carset, explains in the readme of cars how to use more than one material.
