Is it possible to have a headless server build running in my main editor, and have player 2 and player 3 be the full windows build (not headless)?

You can do it that way. You can also use Play Mode Scenarioa to start a external server instance

Can I do that without swapping back and forth between my headless server build and my windows build? This is where I'm losing a lot of time recompiling and stuff.

#

I'm currently manually clicking "switch build profile" and then running it, and then switching back. Suboptimal. lol

yea. I might have to rebuild for any changes to apply though

Follow-up question. Is it possible to do my play mode scenario where I have my (local) dedicated server headless build, and two player builds, and then somehow attach my debugger to the sever build?

It looked like I couldn't attach my visual studio debugger to the server when I was trying a 3 local instance play mode, maybe I need to have the server running in the editor instead of a local instance?
