A Humble Noob Requires Assistance

Ok, Ive got Wc3 Image Extractor and Ive opened the skin of the ghost blood mage, I have the right path for it. What do I do next to actually get it to appear where it should be? where do I apply it?

You've already applied the skin. The .blp for the model is the skin. Just assign the model which needs the skin, re-open your map and the model will use your skin.

I assign it to the unit under Art-Model File, right? because when I do that it says "could not load file: Textures\Hero_BloodElf.mdl" and this is after ive reopened the map. I still dont understand

Not .mdl, .blp.

You don't specify a skin under any of the fields in the Object Editor. For an explanation, see the Importing Skins tutorial in the tutorila section, and the questions some other people asked after that.

The skin is for a certain model. You don't apply skins from object manager. The specific model which uses the correct skin will use it in the game automatically.

Thx guys, i understand now, im just an idiot

Heh that was very long and tiring but you finally understood
