Multi posty...
I advise reading the rules to prevent future mistakes like this.
Firstly, import your model.
Secondly import and repath the texturtres correctly.
Thirdly, save the map and restart WE.
Fourtly, make sure the unit / trigger path is set correctly (triggers refering to custom models need to use 2 slashes in the opposite direction).
Fifthly, test and enjoy.
If this does not work, the model is eithor broken or you have made a mistake.
