L4D2 Skybox problems

It looks normal to me…

I started hammer editor to make a map and i saw this

:fffuuu:

That would be because you need to use the l4d2 construction kit, as it differs from the hl2 one…

Is that the authoring tools? or is that something I’ve never heard of before?

Authooring tools, I just did not have the name to hand.

Looks like all the skyboxes are missing, that’s weird. I guess you have 2 choices, uninstall and redownload l4d2, or download an extracted version from a torrent and put the missing files into the game dir.

Let’s say I don’t see the sun in any campaign the has it, like Dead Center (and I think the Parish?). Any fix? I’ve tried all the idea suggested in this thread.
