Report article RSS Feed Source SDK Base - Orange Box released

Source mods can now run from the Orange Box engine code without requiring an Orange Box game.

Posted by Varsity on Feb 24th, 2008

The Source 2007/Orange Box version of SDK Base, from which Source mods can run for cross-game compatibility, is available now. To use it simply change your mod's AppID to 218 in gameinfo.txt and restart Steam. If you have custom binaries, you will need them to have been built with the beta SDK code; access the beta through Steam > Settings > Beta Participation.

SDK Base Orange is only a 10MB download on top of the old SDK Base. Unfortunately it doesn't yet provide access to any shared Episode Two content, but that's most likely an oversight on Valve's part.

To install the new SDK Base through Steam, click here.

Thanks whoever attached this to Source. I didn't have the right permissions for some reason.

Does that mean you can create a mod with only HL2 in the search path (gameinfo.txt) that support HDR if you export an existing HDR skybox in it ? And Motion Blur ?

I used the create a mod thing and chose Half-Life 2 Single Player for it to be based off. The SteamAppID is 420 not 218. What do you mean we need to change it to 218 to get it working?

This AppID tell on which engine and game your mod is based, here's a short list of differents AppID, but you can find the full list at the following link Developer.valvesoftware.com :

" # 212 Base Source Engine 2
# 215 Source SDK Base Temporary ID, used to mount the Episode 1 engine in mods
# 218 Source SDK Base 2007 Temporary ID, used to mount the OrangeBox engine in mods "

The wizard hasn't been updated with the new ID yet. Your mod will work with 420, but it'll require Episode Two specifically.

No mods will work until they've been upgraded by their programmers. This is the first engine update to break compatibility.

Source 2007 is more efficient, quite aside from the addition of multi-core, but also has new and more demanding features. (I sound like a sales guy!)

I can't wait to put some Motion Blur and dynamic shadows in a mod O_O . It would be awesome if Black Mesa Source use this version of the engine.

Indeed, I myself would like to know how to get dynamic shadows working with lights!

I was trying to do that earlier. env_projected texture does the job, but it has a bunch of bugs that aren't present in Episode Two. I think it might be deprecated.

All you need to do after you install it is open gameinfo.txt in the main folder and change the AppId to 218.

Keep in mind that unless they're using the Ep2 codebase though, there will almost definitely be problems due to changed structure and different code for effects, particles etc.

It wouldn't even run if they weren't using the new codebase...but they are. ;-)

The 'Dynamic Shadows' are a bit of a weird thing. There is a new/modified shadow mapping system (which you can see with the flashlight) but there is a hardcoded limit of 1 shadowmap to be rendered at a time, so IOW if you're using the flashlight you won't see any others. This can be modified to have a higher limit, so you can use env_projectedtexture to create some effects (for instance this could be manipulated to produce an effect like the lights in FEAR casting a pattern on the floor) and things like that.

So how do Valve avoid that in Ep2? There are uses of the new lighting throughout, but I never had any flashlight problems.

I have a serious problem here: I'm making a mod and i've alredy added some custom code to it (i mean in c++) and with the hl2 engine it works fine BUT if i change that little number to 218 it reallly seems like it's on the "ornage engine" (options). So i start a map and what i see is the base hl2 (or ep2) game. None of my changes can be seen for example none of my weapons. PLS HELP
