NPC Problems (First Time Ever Attempting to Make NPCs)

[MARIOGUY789]

Hello, as you can read by the title, I've been having a bit of trouble making NPCs in Garry's Mod (and that it's my first try). The NPCs I am trying to create are ports of some Imperial Officer playermodels from K. Strudel (in the description of these addons, he states that he fully encouraged people to make NPCs out of them).
So far, I've managed to get mostly everything working, except, of course, what I'm currently writing about.
To get to the chase, my problems are the following:
Some of the NPCs which I labeled in their spawn tab (Cadet and Subofficer) are not showing up there

2. The Captain and Colonel models do not show up when I spawn them in (Colonel doesn't even have a weapon model when it's spawned)

I was provided this error when trying to spawn them in: Requesting texture value from var "$basetexture" which is not a texture value (material: pp/copy)
(Again, these are not my models, so I don't know how to fix that)
3. When approaching the hostile NPCs, they have no T-Pose, nor Melee animations
Finally,
4. None of the NPCs make any sound when firing any weapon or when moving around (there are no footstep sounds)

Again, this is the first time I've ever attempted this, and I'd just like to be able to get some assistance with these problems so that we can all have fun, because if this goes well, I'll upload all of the packs to the workshop.
Thanks

Shouldn't this be posted on Its proper subforum?

My bad. Not used to navigating to many forums. How can I remove this from here and post it there?
