Honey select noob here trying to mod it for the first time.
How should i go about it?
Well bud, I'm gonna be honest, it takes a couple of tries, my best advice is get HSResolveMoreSlotID, it's basically a program that gets you mods, and tells you what basic mods you have. And last I checked which was years ago, it helps you solve and automatically downloads most stuff. But this game has suffered losses, outdated mods, etc etc. So it serves as a guide.
EDIT. I just realized F95 has "all in one links". Not sure if/which has all the required mods so you can begin installing cards and clothes, but I'm gonna give you an explanation regardless as if that link didn't exist. Ask someone else, maybe there IS a shortcut to all the crap I'm about to tell you.
I remember I downloaded a pack of mods from the Illusion discord channel on a pinned message. I reccomend you check that out. That actually allowed to work things that didn't work before.
For example this tab of resolveID has all the important mods. In this screenshot you can see I kinda skipped some for studio neo, since I don't use it. And all the important plugins. I often turn on and off LRE for personal preference. And I personally reccomend CMMOD so you can add ahegaos mid scene.
Now when it comes to installing an individual mod, for either the game or a card (girl), once you download it simply place it on the main folder, you'll get the hang of it. For example, let's say it's a girl with complex mods (after you've already installed the game mods) you should get a handful of folders and files you simply need to place on main folder and it automatically merges. Another best advice is check out and download a card from ROYMODS and read the explanation there on how to make that particular card (girl) work and what mods it needs. After that it's just downloading and placing in that folder. I think installing mods from Roymods is like the basic training stage on how to get a feel for mods and cards. But I really reccomend you fully mod your game. So don't invest too much in editing your characters until you have a fully working and modded Honey select game because you can potentially ruin it. In fact, I gotta make a backup of mine. Don't wanna lose my game.
And this little bit here is the tab to see what mod you are missing on a particular card. As you can see it's not perfect but you it can help youget the mods to make your cards work in it's most part. Like face, makeup, tattoos, eyes, etc. To the least important part, like clothing. You can see in each of my cards there's like 2 errors. Those are usually clothing mods that can't be found anymore. Nothing important.
This tab for example tells you about less important mods like clothing and stuff. Tells you the link to download, some are outdated, some you won't use, some are for studio geo which i don't use. These are basically third priority, after you can already run pretty much all of your cards. We're talking about clothes, blouses, shoes, adornments, etc. If your girl looks like it has devil eyes or a broken face, then you might wanna look into that before you install these.
But like I said, most likely f95 or the discord channel still have like a 70G download with all the basic mods. I'd look into that before you listen to me and before you start getting cards or other mods.
