Undertale/Deltarune NSFW mods?

I figured out how to replace Sprites in game with custom ones.

However, I'm having some trouble making walking sprites plus side view sprites for Susie that don't suck so if someone could help me out there then I would really appreciate it. You'll only need to make the one sprite for each (one for walking, one for side view, etc.), I'll edit it to make all the variants.

Given Susie's implied bad home life, her not having any clothes to show up to school in seems fitting.

Here’s some amateur male lewd sprites I did of Virovirokun from Deltarune Chapter 2. These edits don’t deviate a lot from their original designs, since I wanted my lewd sprites of Virovirokun to be accurate to Deltarune’s art style, and this is also the reason why my design of Virovirokun’s dick is just a triangle since Virovirokun is made out of abstract triangles.

Very nice, I like your logic behind the dick. Viroviro has always been a favorite of mine.

OP you said that you were in a Discord server with the original artist of that Susie sprite, so if that's the case do you mind trying to get the to make some more sprites for the purpose of the mod? I don't use Discord for personal reasons so I wouldn't be able to ask them myself.

I think you're mistaking what I said as "I'm in a discord server with the artist, we chat everyday," when it's much more accurately "I'm in the artist's public discord server to get pings when they post." Nobody likes getting unsolicited dms asking them to do stuff for them.

Ah, Fair enough then.

Made the sprites for Susie facing left and right, based them on OP's concept while matching changing it to more resemble the forward and backward facing sprites (changing the colour palette, removing the nipples (might add later on tho), making her taller to match the other sprite's heights and I also made her stomach slightly bigger). 

Next up I'm gonna be doing the different sprites that use the directional sprites but with only slight things changed (like the animation of her eating chalk). Let me know if there's any changes that ya'll would make and I'll take them into consideration.

I just realized that your Susies have a vagina, but no nipples. Are they meant to be inverted and the dark shading patches where the nipples are are just areolae?

Not really, I guess it’s more like she just doesn’t have any? The original sprite I used didn’t have any which is why I didn’t give the side sprites nipples either (same with her not having a tail), but like I said I might end up adding them in the future.

It's so dumb too because they're so inconsistent about it. Their reasoning here is because it has "nude characters interacting with underaged characters" which is already stupid because it's not like Frisk particularly looks like a child (they barely look like a human at all in my opinion) but nude mods for games like FNAF where you play as a much more realistic looking 8 year old, now being chased around by nude wolf girls, are perfectly fine, and even front page material. To be clear I don't think either should be banned, because I think censorship is bad, and because I think Roxanne Wolf is hot, but I wish they'd just pick a side so a better site could take it's place permanently.

It really is stupid. Regardless of how canonically old the other character is, it's just casual nudity. There's nothing explicitly nor inherently sexual about plain old natural nudity.

 

Their forbidden scenario ruling irks me because not only are they vilifying nudity, they're implying it's on the same level as actual sexual content based on how they took issue with nude characters simply interacting with young characters despite no sexual context. 

 

It says a lot about them if they view nudity as a form of seduction, assault or whatever when the context within the game is still the same with the only difference being that one of the characters just so happen to be nude and that's literally it.

Here's some amateur nude sprite edits I did of Noelle (I only edited sprites of Noelle from Deltarune Chapter 1), I tried to make my nude Noelle sprites almost as similar to her in-game design as I possibly could, and I also wanted her color palette to stay the same in her nude design. I also made two versions of these sprites. One with Noelle having brown belly fur, and one with Noelle having white belly fur.

It's not explicitly NSFW but I think it's appropriate to post it here. I played a really interesting Deltarune mod called Rookierune, based on that Kris comic turned into a Tasque Manager copy or something like that. That said, I decided to make a version for Undertale, I made some sprites but they'll probably go through changes, since I always find problems with my sprites.

So far I've done all the variations of Susie's Darkworld sprite when facing forward and I've begun work on her Lightworld sprite (I'm not sure about the colours for that one though).

I think I might have fucked myself over by using this sprite because of the width of it. I've been trying to make a walking sprite for this, but the original Susie sprite is 26 pixels wide while this one is 25 pixels wide. The reason why this screws me over is because of this part below the little heart (Made it green to highlight it.)


The part of Susie's sprite that separates her torso from her legs is two pixels wide, and the line dividing the legs reaches up to but stops short of a different side depending on the sprite. This fucks me over because the sprite I used is only a single pixel wide and reaches right up to it. This makes making leg sprites that actually look like it's one leg going in front of the other really awkward to make. I'll keep trying, I don't want to abandon this idea, but it'll probably be a while before I make something that looks good. Anyone else here is free to have a crack at it obviously, but it'll probably be a while before anything new comes from me. All other images I've posted on this thread are the actual size of the sprites, so feel free to download those if you want to give it a try yourself.

I decided to take a crack at making nude sprites for Susie and I managed to make some quick nude sprites of Light World Susie walking down (that are close to her in-game art style and color palette).

Very sorry I've been MIA for a few weeks. I just needed to take a break. Glad to see this place has been active without me, though. I haven't got much to show in terms of updates, but I can show this:

Every main character has at least one sprite now! (sans, Papyrus, Undyne, and Asgore ONLY have the one sprite but hush!) Makes you realize how much of the cast is completely white when you take all of their clothes.

I can also share that Frisk's spritesheet is 100% done, with the exception of multi-character sprites like hugging Toriel of Asriel. There's a special surprise under that black box in the corner that I can't wait to reveal.



I've made some other progress on just random miscellaneous sprites, but it's nothing consequential enough for me to show off yet. More updates are definitely on the way.

Very well done!! She is adorable here! I especially love the white fur alt, as it helps break up her fur pattern a bit. Her tail in those back sprites is the cutest. I think her boobs in the forward sprite look a little too big given how flat she is in the sideways sprite, but I'm also not sure how you would fix that with the small sprite size, so it's probably fine. Are you modding these into the game yourself or are these screenshots just edited with your custom sprites?

Also well done! I think she'd benefit though from a bit more stomach like in the original edited sprites though. Susie wears very baggy clothes to hide some of her figure, so it might make it look a little more natural if you added a little thickness in her waist area like this, even if it's slightly less accurate to the sprite. Still nice job!

Thanks, but I prefer my design of Susie since her figure is based off of these real Susie sprites from Deltarune Chapter 3.

 

 

 

 

 

Edit: Oh also here are some Dark World sprites of Susie walking down. Her body and legs might need more shading though. (Apparently the sprites of spr_susied_dark are one pixel smaller than the sprites of spr_susied)

What's your process? I've been editing the entire sprite sheets from The Spriters Resource and then uploading those into UTMT as embedded textures, then manually searching for the sprites I need to update in the program and updating their sprite positions to match my custom spritesheets. I know there's other ways to do it, so I'm curious if your way is any easier, because mine is sort of tedious.
