Can you only give a unit the hero glow by editing the model? Sorry if this question comes up alot, but I don't see an answer to this question in the other pages of this forum, and I didn't get an answer when I asked in another thread, so.....
You can trigger it (look for models inthe DL section) to attach the origin of the unit, although his won't give weapon glow. The best way is to convert the .mdx to an .mdl and add hero glow that way... there's a tutorial on how to do that, although I haven't read it so I don't know how confusing it is.
No, it is way too confusing, he wrote the tutorial poorly, using many pronouns for which he did not refer to the antecedents, which he commonly does, over and over.
