Now this is the part were many people make errors.
Open the file (the mdl version) using "
Vertex Modfier.
Often the weapon is found on the first Geoset so type 1 or click okay when the 1 is visible.
Select the "
add button" and select the vertex points of the weapon you wish to use.
This part may take a while and be frustrating for those who find searching difficult. Just examine the model. You can look at it in wireframe by viewing the model you extracted using the "
Wireframe mode" button to toggle the wireframe view within
wc3viewer.
Delete the selected vertex (hopefully its the model, if not, press undo "
Ctrl+Z". Or either reopen the model (if not saved when you made the error).
