I wasn't being defensive. I was merely telling you how to get around it. You didn't properly read what I said. While the Game Capture is also a global source it is not a source you can only add once. Game Cap 1 is not Game Cap 2 is not Game Cap 3. So like I said, you can add a second or a third or fourth etc. game capture all with different settings. You can also set different hotkeys for each and every single one of them to capture the games. In order to do this right you need to start looking at what you are doing when adding a source in a different scene which should be pretty obvious but it seems you seem to make a mistake somewhere. When adding a new game capture do NOT add an existing source. Add a new source with a different name and set up the properties for it accordingly. Don't have the "Capture any fullscreen application" selected under mode.
It may be shitty to set up depending on how many different captures you're using but once that is done it is done and you only need to press the hotkey to capture your game. This is a work around for your capture problems not a defensive statement (though this statement about it not being a defensive statement is slightly defensive). Setting up a stream is not done with just a snap of the fingers it's a hindrance. That hindrance takes some time but if you do it right you won't have to look at that stuff anymore and the hindrance is gone. And Harold is right though, most games do work completely fine with OBS. I have has as backup DxTory running so I can press the capture hotkey for that and it still ends up in OBS.
To answer what purpose other scenes have when you have global sources:
- Intro/stream start + webcam
- Game (with how many game unique captures you want) + webcam
- Intermission (with small window of the game using the same capture of the one in the game scene)
- Something with community stuff maybe + webcam
- Stream end + webcam
By your words here I believe you have also missed the possibility of having an entire scene in another scene. I make good use of that feature. I have only 3 (or technically 2) scenes you will ever see in my streams but each of those scenes are composited together from other scenes such as my Overlay, Transition capture, Webcam + animation and the Winamp visualizer to name a few.
Scenes are just a good way of managing your workflow. You could also use one single scene and go through the hindrance of turning sources on and off for different purposes but that's more tedious than having multiple scenes, Just know how to set it up correctly. If you need some help with that without being passive aggressive like in your last post I'm willing to help out. Just tell me exactly what the problem games are and what kind of settings you have to use to get them to show up.
