Question / Help How to screen crop using studio

Relatively new OBS user here (using 17.0.0). I want to setup a stream with an overlay, such that the cameras on screen will be located in the various boxes of the overlay image. I am having issues cropping or selecting the parts of the screen where the cameras will go however. I have seen in prior versions of OBS this being done, whereby the sub-region function was used to select various parts of the screen, thus fitting them into the overlay image. But for some reason, I cannot figure out how to do this for studio.

I have seen ALT + dragging as a solution in some cropping areas, but I don't know WHERE to ALT + drag (i.e. what screen should I be in, in order to have that work?). I have also seen setting global sources as a potential solution, except I can't figure out where global source would be in the new OBS studio.

I guess my main question is: how exactly do I crop parts of the screen in conjunction with an overlay?

Sorry for the noob question!

As for alt+mouse cropping, you should aim precisely at the center of any red circle of the bounding box of the source.

Thanks - so the specific issue is that if I have one source (my display), and I crop something from it (a camera location), it won't let me use the same source again, without using the original crop. Maybe I am missing something, but in previous versions, it seemed like you would be able to capture multiple sub-regions of a single monitor, and they would act as their own source. (this is where I got this idea: https://www.youtube.com/watch?v=atrCiyDbrdI&feature=youtu.be)

Is that possible in studio?

You can add source (choose Create new), crop it (ALT+Mouse), than add same source (choose Add Existing), re-apply the crop (ALT+Mouse).

You are my hero - that's exactly what I was looking for. For some reason, when I tried something similar before, it just kept giving me the previously cropped version.

Thank you so much! I thought I was going nuts.
