Actually, this is more like a testing stream, because, I'm going to work on the background. But, to do so, I have to use Photoshop.
However, for some reasons, OBS doesn't work with Photoshop CS5 as the way I want with Paint Tool sai or Clip Studio Paint, and it doesn't show the screen capture with photoshop. I made some settings for this case, so I hope that this time works.
