Because I've just made this for a guy at sc2mapster, I will post this here, too... just with better text between the pictures...

MODEL & his ANIMATIONS:
You can access the model previewer previewing a model with right clicking an actor and model and selecting "preview model".

^ That's how you easily get to the previewer...

The previewer shows you the unit and its animations.

^ The previewer basics...

HOW TO IMPORT A WOW MODEL with the WoWModelViewer...
-Get a WoW installation and get the model viewer from HERE.
Chose the Binary file for your operating system and install it.

In the WoWModelViewer you search and chose a model, select a texture, preview the available animations for the model and open the Exporter Options. Set the scale to 0.5, tick the animations you want and rename them to names Starcraft 2 understands...
If you need animation variations use "NAME 00", "NAME 01", ...
The default names an unit's animations should have are Death, Stand, Attack, Walk.

^ Settings for the export options.

Then export it. It will export the model and all used textures (the one you selected).

^ Export it.

Import the models and textures to your map and SAVE IT!!!
Duplicate a model in the data editor, change the model file's path and use the new model in an actor. You might have to play with the scaling to fit the unit in correctly.

^ importing rules and further stuff you can do

If you did everything correctly, your unit in the model previewer might look like the one in the second screenshot.


I DO NOT UNDERSTAND... WHAT NOW?
- Ask questions here or read another tutorial like our Tutorial in GalaxyWiki or Molsterr's tutorial on sc2mapster.

Nice job you should add this to the wiki.

BTW does WoW have normal maps and emissive maps?

The models I've exported didn't have that stuff. So I don't think that this stuff is inside.

I know that the wowmodelviewer exporter doesn't export normal maps, which is why I asked if WoW uses them. I'd be surprised if it doesn't, and it would be important to note in the tutorial that you'd need to apply normal maps separately.

You can fairly easily make normal and emissive maps for the models but you must use 3ds max to convert and not the viewer. WoW does not have them normally; use nDo in photoshop to make normals.
