Awesome tutorial, now I just need to figure out which steps I can skip since all I'm doing is adding a non-animated weapon model to my hero's arm. I have to recheck everything because instead of getting the weapon model on my hero I'm getting the placeholder sphere and if I try to place the unit in the editor it doesn't have a model either. Something I did nuked the model because I copied the unit, actor and model from it's non-attached version (item drop for the player to pick up) and the model shows up.
Edit: Guess I should try the 'easier' attachment tutorial that doesn't include 6 attachments that have missile based attacks.
Would it be possible to pose a link to the other attachment tutorials on the front page, I didn't even notice the easier tutorial until after I tried to do it the hard way and made a post here.
