Use wc3viewer or some other MPQ browser program to find out which skin path your model uses. Then you just import your new skin using that path and it will replace that standard skin.
with warcraft 3 viewer you use the treeview to open the model that it uses, and then under the 'current file' tab you can see 'show used texture names'. It'll have a bunch of textures probably, but you only need the main path (for example with the arthas model the main arthas texture is 'Textures\Arthas.blp')... you just set the skin path to whatever that is.
If you are importing a custom model that uses a custom texture then you set the skin path to whatever it says to where you downloaded it from. Most sites that host skins have the correct paths listed for you to use.
Yeah, that's because you are opening your custom skin...... use the treeview to open the MODEL that your custom skin is supposed to go on (in this case open the ghoul model). When you do that you click on those tabs to show you the skin paths for the standard model, then copy the path and use it as the import path on your custom skin in the world editor.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
