Models turn to errors

[Blakeguy25]

So every model on my server turns to an error client side. I have every file added with "resource.AddFile("")" and when I join the server it shows that it's sending me all the models but when I finally join the game, every custom model becomes an error.

I haven't identified for sure but I believe this is server side, not client side.

Please tell me if I am missing a step here:

1. I downloaded an addon (for example Slow SNP Pack 4)

2. I used a model in the pack just fine (but I had the addon save to my server and client)

3. I deleted the addon from my client and used
resource.AddFile("")
for every model, material, sound ect.

4. I join the server from my client without the addon, and it shows that it's downloading everything I added as a resource file

5. The model is a big fat error?

6. I seek help lol

Please help me, any help is appreciated! Thanks
