Adding world portals


I assume this is probably a bit too much to ask, but adding world portals (like in Portal 2) would be amazing. Even though of no use in the single player campaign it would be a great feature for mappers.

In case somebody doesn’t know what a world portal is:


This actually would help with a number of maps that don’t quite fit together (I’m looking at you, c1a2c…), but I have no idea how these would play with Black Mesa’s substantially different codebase.

The effect can in many cases be faked with hidden trigger_teleports- take a look at bm_c1a4c or my upcoming pd_c1a2a for examples of this.


These were used to great effect in Portal 2, but it seems like it is a feature for that specific branch of the engine, which I doubt the devs have actual code for.
