Importing mdx to DotA maps

[memory44]

Hi! I am making my custom hero to DotA maps. I want to use custom model/projectile I downloaded as .mdx file. Using MPQMaster, I add the file to war3mapImported folder, then editing the humanunitfunc.txt / unitui.slk to use .mdx file like :
Filename -> war3mapImported/custom.mdx
unitui.slk/file -> war3mapImported/custom
humanunitfunc.txt/Missileart -> war3mapImported/custom.mdx

When I play the map, the model is not shown and shown as invisible like unit (I can only see the selection circle). Is there any trick to add custom data to the map?
Thanks for your help.

Did the model come with a .blp or .tga file with it? o_0

nope. I just got a single .mdx file.

with this file must be .blp where the hero is drawn and mdx is only animate this picture like strike respawn death and etc.
