@Anthronia I figured someone might say this so it's here on this site it's called the Cutscene Player https://www.gta5-mods.com/scripts/cutscene-player by HKHKH191 (You'll definitely need this for it to work)

(I can make a video about this and show you it on my YouTube channel to save you the hassle just lmk)

If you want to know how I did it with my multiple characters like this on the screenshot I did.

Follow the steps below: (But read this before you attempt it because some crucial things I will have to say) and it's a lot to READ:

1. (Download Menyoo Deprecated or newer maybe I'm not sure because I use the deprecated one if you haven't and it's important that you do have it) (Download Simple Trainer if you haven't so because it will makes things 10x easier to recruit them as a bodyguard I will mention this again in this step below at some point)

2. Play LSPDFR-(This is crucial)

3: Have 2 custom made characters you have on LSPDFR (Sync or not but preferably I have mines Synced)

4: Now use one of your own LSPDFR custom character when you spawn in or you already have it preset beforehand. Open up Menyoo and copy and paste your own character that you're using currently. Your Copy and Paste character will be there when you switch over to your 2nd character but make sure to remember your location if you spawn somewhere else. Once you spawned in copy and paste your 2nd one use Menyoo and drag your character to where your first one is so that way it's easier. (Doesn't matter if you're loading into Director Mode or back to Story Mode both will still be there just remember where you place them)

5: Open up Rockstar Editor and go to Director Mode and use both your online characters and repeat (Step 4) Obviously without the LSPDFR to make it make sense just incase anyone reading this but you can do the same way with LSPDFR custom characters but preferably I would do it with your online custom characters from Director Mode because I think you can have only 3 custom characters for LSPDFR if I remember correctly but either one works however you want it.

(Read This before you attempt Step 2, 4 and 5) (If you have both online characters from the base game with your preferred genders and facial features and clothes then you can skip read this but I'd make sure to read this for the first time)

(If you don't have any online characters that you made from the base game you'll need to temporally uninstall your ASI Manager and create both of them to your prefer customization and then you can reinstall ASI again afterwards since everything will transfer towards the modded version and you should still see both your characters features and clothes that you had from the base game) (Do the same thing for Step 4 Copy and Paste but you'll most likely will have to do your LSPDFR characters 1st and 2nd characters again if you don't already have your other 2 online characters beforehand.

6: Use one character that you're not using and not going to Copy And Paste and play with it because you'll be leading it as your main character within the Cutscene while your 3 others will be your NPCS.

7: Recruit them as Bodyguard using the Simple Trainer.

8: Open up Cutscene Player (Go to the Online section) pick whatever cutscene you want to use that you'll know that will show your 3 Bodyguards) (But do get familiar with it first if you haven't use Cutscene Player Before and play around with it a bit to familiarize yourself with it)

9: Whichever character your using currently to play as make sure to set the option to these

Replace MP1: Replace MP1 With Player-(Which is yourself)

Replace MP2: With 1st Bodyguard

Replace MP3: With 2nd Bodyguard

Replace MP4: With 3rd Bodyguard

10: Play Cutscene and you're done!

(Issues I've Encountered while using the Cutscene Player from HKHKH191)

Don't skip the cutscene and just let it play out majority of the time but sometimes you can skip it but although if you're unlucky you'll get a infinite black loading screen if you decide skip the cutscene fast enough or too early and you'll have to close your game entirely and redo everything with the copy and paste.

Your bodyguard and NPC could look out of place with different outfits on. It's best if you create a duplicate of your bodyguards and yourself incase something happens.

(Sorry for the long post but I had to make it thoroughly for people to understand nowadays)
