looking for a modeling program that retains everything from mdx files

so like able to import all the info, animation, etc, what is the best one for it without errors or as little as possible

also, will the newer versions of 3dsmax work with mdx?

new versions of max can import mdx, but only the mesh I think.
Best way to do it is with max 5 and art tools, check BlinkBoy's new tutorial.
