Pick up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people, people he cares about, are counting on him.
Propper is an add-on for Valve Hammer Editor that can convert any map geometry into a Source model, suitable for static props and physics props.
Propper is an edited version of vbsp that outputs a model instead of a bsp.
Many mappers need to make props for their maps, but don't want or dont have time to learn a separate modeling program. This tool allows them to make models in Hammer in a one-step process. It's also useful to modelers who work with mappers. Propper keeps texture mapping intact, and auto-generates a physics mesh.
