Okay, so i haven’t been mapping for Portal for a long time now, and i have decided to start again. I followed a guide on thinkingwithportals.com to get prefabs, and the fgd and stuff…
But i’m stuck. The guide tells me that i should go into Source SDK, and create a singleplayer mod of Portal. But when i open the Create a mod wizard, i can’t select Modify Half-Life 2 Singleplayer.
Why is this, and do anyone have a new guide for Portal mapping?
why would you create a singleplayer mod of Portal to map? Why not open SDK, select Portal, open hammer and map?
I need the prefabs and fgd (or, thats what the guide said 
)
you can load both of them in hammer
that’s true
