OBS for Theatre - Scene Switching

Hello! Incredibly new user here. I teach theatre in North Carolina, and am working with OBS to stream productions for my school while we are in quarantine. The Skype NDI input works well to pull in different actors from different locations. However, I've got a couple of questions that I have not found answers to on the forums, and would appreciate your guidance.

My ideal situation would be to have a list of Scenes for each moment in the show that includes the NDI camera stream for just the actors in that scene, along with any general background image for the scene, and any music cues in that scene. However, if I break the show down into scenes each time a character enters or exits, I end up with 118 Scenes, each with 3 - 7 sources in each. Would OBS be able to handle that number of scenes easily? Is there a better way to do this?

Additionally, the ideal situation would be for OBS to cue up the next Scene in the list once each new scene is triggered, but this does not appear to be automatic. This is how lighting cues and sound cues run in the systems my students use (cue 4 is cued up, hit go, cue 4 plays and cue 5 cues up), so it would be the easiest to train them on, and decrease accidents. Is there either a setting or a plugin that would allow for this? As I recall, this does happen with vMix, so would that be a better choice for us to use?

Thank you again for taking a look at this. If there are threads on the forum that already address this, I do apologize; just point me in the right direction and I'll try to find them. Thank you again!

OBS can handle 118 Scenes without issue, though it may slow down the startup as the scene file is parsed (the more scenes and sources in those scenes, the more it has to ingest).

There is no 'slide deck' for an automated sequence of scenes. OBS is meant to be a live-production tool, rather than pre-scripted.
Some people have set hotkeys for certain scenes and then used third-party software like AutoHotKey to create a hotkey order script... it's unlikely this would work for 118 scenes (just coming up with unique hotkey combinations would be a pain), unless many of them could be re-used. Even so, not really a great option as it would be very complicated to set up or maintain.

The simplest method while live would be to just create a list of scenes, name/number them in order, and use Studio Mode to cue up each in order, going down the list.
Alternately, have each individual set of scenes in-use, and a paper cue sheet for the OBS tech to follow on what the next scene to cue up would be.

I have definitely had a 100+ scenes some with at least 10 sources with all the nesting I do to do cool things. I've never had a problem unless my RAM is being eaten up by something else though my computer is pretty beefy. I reccomend using OBS Transition Matrix for managing transitions between scenes if you plan on doing different transition styles. Definitely number or name your scenes and put them in order cue 1 at the top. Then set a hotkey for the transition button and you can just use the down key to load the next scene into preview. There is no way to autoload the next scene in a list into preview without a bit of coding
