Here is the MDL importer for 3ds max and maybe gmax, I have yet to test it with gmax. There are still errors as it is still in it's beta stage, but I just wanted to release it to help out the people who needed it.
maybe im just unfamiliar with the gmax program but it didnt work for me. It didnt even say anything.
What i did:
first i opened gmax then i went to the dropdown menu maxscript and then run script, and i chose the MDLimporter.mse, after i click ok it goes back to the main modling environment and says nothing and does nothing. Please help if you can.
