imported models named mdx converting to mdl wtf help me O.o

i follow the instructions and i change to model to the imported file... but then in the editor it says .. .mdl instead of mdx
why? and also i've never really figured out how do get your skins to work, someone help me plz ^^

it's nothing wrong with that, man! That's how it works. Did you actualy try and test it?

And for the skins to work, check out the tutorial section!

When the game loads an mdx it seems to convert it to mdl internally and that's what it actually reads, so you use .mdl in the paths
