Source SDK Release Notes

Current Known Issues

• The sourcesdk_content folder is not getting updated consistently so we suggest renaming your 'sourcesdk' and 'sourcesdk_content' directories before running the new SDK the first time. We will update the SDK Launcher to get around this problem but this is the workaround for now.
• Some users are getting 'Unable to load FileSystemOpenDialog.dll' when running Hammer. Follow the same instructions as above to remedy this.
• Hammer 3D Ray-traced Lighting Preview performs very slowly and should be avoided.
• Hammer 3D Lighting Preview does not work with some video hardware.
• When running the Orange Box versions of the 'studiomdl' and 'vtex' you should include '-nop4' on the command line to bypass our Perforce integration with these tools. We will eliminate this need in a subsequent release.

See Source SDK Known Issues or Bugzilla for a more complete list of known issues and workarounds.

Enhancements

SDK Content

• Map source for Portal level 'testchamber_a_05' is included for reference.
• In order to support multiple versions of the SDK tools the directory structure underneath 'sourcesdk\bin' has changed.

 'sourcesdk\bin'              - contains binaries needed to run the Source SDK launcher
 'sourcesdk\bin\ep1\bin       - contains Ep1 engine compatible versions of the SDK tools
 'sourcesdk\bin\orangebox\bin - contains Orange Box engine compatible versions of the SDK tools

SDK Launcher

• SDK Launcher can run either the Orange Box compatible versions of the SDK tools or the Ep1 versions. The newest tools are run by default, but specifying '-engine ep1' in the launch options of the Source SDK tool will have the launcher run the previous versions of Hammer, Faceposer, and Model Viewer.
