Mapping for GMod - Hammer hates me. - Help

Well, basically I get the classic "missing material: editor/wireframe" fatal error when loading Hammer with the GMod config. I'm using the hammer.exe in Source SDK 2013 Multiplayer, tried the Singleplayer one before which also had the same error. Config is as follows: [IMG]http://i.imgur.com/cW9IaND.png[/IMG] [IMG]http://i.imgur.com/oZ62JDX.png[/IMG] Anyone able and willing to help me fix this issue for good and forever? I don't mind installing Source SDK again, if I need a different version than the 2013 one if that's the solution to permanently fix it.

Hey, I see that you want to map to gmod, avoids the sdk 2013 multiplayer because it and not for gmod, used the singleplayer, Is the more you get the error,

Use the CS:S or HL2 hammer. It's the only way.

I know your pain. Hammer is a bitch to set up but, it will slightly pay off once you get it working. (Hammer isn't the greatest tool out there)

The HL2 one cannot even start because it tells me that "steamapi.dll" is missing. I got HL2 by buying the Orange Box, if that info helps...

[QUOTE=Robotboy655;46561547]Reinstall HL2 from scratch from Steam, not from the orange box DVD.[/QUOTE] Including the episodes one and two?

Yes. Remove all of them and then install again. OR delete bin/ folder in Steam/SteamApps/common/Half-Life 2 and verify HL2. Should fix hammer.

Ok, did all of that as described... Removed HL2 + episodes + Lost Coast, reinstalled it by downloading it via Steam and set up the GMod config in HL2/bin/hammer.exe as usual: [IMG]http://i.imgur.com/GCOvkV4.jpg[/IMG] When using the HL2 config or any of the episodes configs, the grid loads perferfectly fine and no missing material wireframe error pops up. But when using the GMod config as shown above, it gives the error again. Any idea please on how to FINALLY fix this shit...? It's getting frustrating to see how theres thrown out shit tons of maps on the workshop everyday but then seeing how Hammer won't work properly...

Don't use GMod config, compile the map for HL2 and copy it to GMod.

But don't HL2 and GMod have different scales and maximum map sizes? Because if that's not the case, then I wonder why there are special configs for GMod...

[QUOTE=Oldrid;46574378]But don't HL2 and GMod have different scales and maximum map sizes? Because if that's not the case, then I wonder why there are special configs for GMod...[/QUOTE] No. The configs are to use GMod entities, models and textures.

You mean like the PHX textures and props, which are included in GMod now? Because except that, the game itself doesn't have much to offer on its own since the rest is from HL2...
