Like Source SDK hammer?
No, an earlier, less resource-intensive (and with less attitude/bugs) version of hammer/worldcraft (3.0 I think). Because the machine I'm using is boned, hammer can't access the registry or something, and can't save the settings, and won't export properly. You *can* use the newer versions of Hammer, such as that featuring in the source SDK, but they're really not designed with non-source games in mind.
