How the hell do i add models so it downloads clientside?

It’s in the name.

I have put them in my servers addons folder, i even extracted the models and materials to the main garrysmod directory. Whenever people join they see an error. I have put the files on my Fast Download also.

Hmm. Is your fastdownload configured correctly otherwise? Did you turn off downloads in your server options and set your fastdownload url?

What’s your FastDL? Did you add resource.AddFile to your lua?
sv_downloadurl ?
sv_allowdownload ?
sv_allowupload ?

Post it right section?
Yeah, please.
