oh sorry, forget to mention put the textures to this folder: Assets\Textures, it will work (select all textures, right click, move files, new path and write Assets\Textures, then click ok, then save close,open again then import model, completed)
Sad, but you can't export NPC-s, if you want to make a similar one of them, then go to the characters, chose the race/gender, make him look like as the npc looks like, export him. note: some of the attachment in him wont exported for example shoulder plates, hat, weapons here is a tutorial about it:wow characters to sc2. For example if you want Putress, you need an undead male character in a warlock T8 set
here is Teron too, but it has a little bug: The shield is untextured. You must find somebody who can make a texture for the shield.
oh and i forget, All the three models ' textures have path: Assets\Textures
well i want to learn how to import then export things. I tried it about 1 months ago, i have the 3ds max, the 3ds object and the pluggins, but when i export the model, then import to the sc2 map, it doesn''t show anything. can you pls tell the username of that person who know it, ask him to help me or make a tutorial?
