Error: Material "engine/occlusionproxy"

[Muzzi16]

I've get this really nasty error when I play maps I compiled myself. (this is dm_lockdown compiled from the vmf included with the sdk)

The textures of other objects are almost always black, and sometimes green or blue.
I can play the standard HL2dm levels online though, without any errors. Because I didn't compile those maps.

The console shows this error:
Error: Material "engine/occlusionproxy" uses unknown shader "Occlusion"

I've tried a lot of things already:
-SDK current game = HL2dm
-I've uninstalled the sdk, reinstalled again.
-Uninstalled everything including steam, reinstalled again.
-Used different options when compiling the map.

Does anybody have an idea, or had the same error?

Got exactly the same error message and black models appearing in deathmatch

i get that error a lot, and i got black models, but i just sorted out my lights, as one was touching a wall. or some walls werent aligned properly, and i could see the outside (void)

i think its mainly to do with lights tho, just check them all

Thanks for the replies guys.

Meanwhile I found two guys at the steampoweredforum with the same error and no solution yet:

@ Albino, thanks, I'm going to check the lights.

Yep, getting that error means you screwed up your lights, and I did.
I finally fixed it few weeks ago.

Remember that the dm_lockdown is most likely not the final version you see in hl2dm, because it still contains LOTS of redundant junk from the singeplayer maps (mainly triggers).

Why is it that on some maps all entities are black sometimes but other times they work fine?
