Just follow the tutorial josepezdj already posted. It's eggsactly what you need and there is no need in this case to recompile the model.
And what do you want us to do now? We don't know what you did wrong. We don't see what files you have. We don't see what you changed.
Oh, wait, I've forgotten to post the files, sry :/
I'l edit them Later in this post, when I'm back at home^^
I didn't check your files yet, but did you edit the VMT's like Josepezdj said? They direct the model to the right vtf when the model uses that VMT. If you don't Change it, it could cause problems like redirecting the model to the original vtf.
I think so, if I understand right how to do that. It isn't even rejected to the original.vtf it simply shows nothing^^
Open the mdl file in Skin Editor, and change the Path to model files to the location of the files relative to models/ . Re-save the model, and Skin Editor will automatically update the name. The model should now appear and work properly in the engine. Similarly, you can edit https://file-types.com/docs/ppt files here as well.
