Would be far better if people moved to SC2 where mods (which are equivelent to an MPQ filled with data) are distributed by the online system on demand.
If you mean this one
It's really good, wow! I haven't seen it before, I've seen some Diablo 2 rogue camp video in starcraft 2 but it was not an actual map. This one is using the WoW inventory system that is built in SC2. It still lacks proper terrains, the Shakuras plates just doesn't cut it, needs medieval plates for a cathedral/dungeon, also needed to make a blur of other texture to make it look dirty and dusty. I did this with mixing grass plus semi-transparent dirt.
It is true that it is harder to make fantasy in sc2 from the point of having to prepare UI, models, and a whole bunch of stuff that takes time and space, in the same way it is pointless to make modern/futuristic maps in war3. But cartoony graphics of war3.. come on.
You can import a warcraft 3 model to 3dmax and export it as a SC 2 Model using a script
Not really... I actually finally reach the point that I had to do since 2010-2011, to convert some futuristic Buildings models in MDX made for me to SC2.
What has to be done - okay if you will transfer animations, it may require fixing either the name or other. For the model and texture itself, quite easy.
Import model if you have MDX plugin, create the specular and normal textures in no time. There are tutorials for normal and specular textures, then use Blizz plugin or current M3 import, export, then simply import the files in Assets\Textures
Now.. where are the eager guys to do something like war3 model editor, had to wait for the tools to even start thinking of such tools.
