How do I fix missing textures?

I’m trying to play in City_8, but there are a lot of missing textures and models too. What do I do to fix this? I already tried the CSS content pack thingy, but that didn’t work at all.
Can anyone help ASAP?

This isn’t solved yet, so don’t let the “marked as solved” thing fool you,

Can you link the map?

It happens with all these maps too.

Why does it say this is marked as solved?

Try with to sub to this and check again
Also there is the “Metro Police” pack too for models

And be sure to sun to all the maps of City_8 on Workshop
