I was exporting a model from blender into garry's mod, when it suddenly, and inexplicably broke. I'm not sure what caused this - it worked fine initially, this only started happening when I flipped a couple normals. Has NEVER happened before, and I have no idea what to do.

I have a video at [imgur.com/a/kaowtLK]
Pictured first: How the animation should look, and second: how it looks in-game. Don't mind the in-game textures, they're unfinished.

Also, if it helps, heres what comes out of hammer when I export the model:

I'm seriously stuck, any help would be appreciated, if this doesn't belong here then let me know because I have no idea where it does belong.

Very simple; I'm trying to export a viewmodel for a Garry's Mod Addon, but only the animations are exporting, with the model just... not existing?

https://imgur.com/wBsUxX3 - My Blender Setup, note how there is a weapon.
https://imgur.com/ole7YuZ - The viewmodel when exported into Garry's Mod, note how the weapon is... gone? That's weird.

I'm pretty new to this, and would very much appreciate help.
