Models in mapping

I am creating a map in the hammer editor for Garry’s mod, but am having difficulty figuring out how to have both Portal props in it, and Half-life props in it. Assistance would be appreciated.

load it up into the hl2 version of hammer, then add hl2 props. after that, load it into the portal map editor, and place the portal props. the collisions on the models probably wont work if you do this though.

Copy over the files from the Portal GCF to your HL2 folder.

How do I copy files from the ‘GCF’?

Use the search function. By god.

Download GCFScape and drag and drop.

If you’re just using HL2 props, you can build the entire map with the Portal SDK configuration. Portal (and all source games) mount the HL2 content.
