Something is wrong with rp_evocity...

Everything is messed up. It is surely no performance issue.
Something similar happens to a couple of other maps I downloaded.
Also at the start a message pop ups saying node graph is out of date.

What can I do to fix this?

First, do you have CS:S?

Nope, I don’t.

That is why. It uses textures from Counter-Strike:Source. Most RP maps do. The only real way to fix this is to buy CS:S.

And EP2.

Uh I see. I have EP2 at least. Is this all?

Should be.

Thank you very much.
