[ILLUSION] Koikatu! - Questions & General Discussion Thread

[AbabaMerumeru]

Sure, here: https://gofile.io/d/7spJqi

Hopefully the issue is just isolated to my version of Koikatsu so when I do get around to updating, it will be fixed.

Unfortunatly the problem is with the headmod itself and the fix is going into timeline like you've done and then manually adjusting both for the position and the scale based on the deault values for the card.

You find them by clicking on the reset button.

This case is pretty easy since by hovering on the nodes we see that they're apparently all setting x/y/z to 0, so just select all, input the values and click on set.

For the scale you would have to proportionally adjust based on the changes being made but just setting them to default looked pretty good already.

No need to update the game though ദ്ദി◝ ⩊ ◜.ᐟ

I want to preface this by stating I'm a complete noob when it comes to scene editing. The only things I know are basic stuff like changing which character is being used in the scene and fixing a collider issue by disabling the dynamic collider by turning off all the affected dynamic bones.

I'm running into a strange issue where the iris seems to be overlayed on top of the faces on certain scenes. I attached 2 screenshots. The first has both the irises and the second one I was able to disable one of the irises so you can see the sclera(?) and how the iris is on top of it. Only certain characters have this issue so I suspect it's the eye overlay or something but I don't know what. Any ideas on how to fix this?

I've had the same problem with some headmods, and I was able to fix it by setting the shader to alpha (Xukmi,KKUTS,Shader Forge, ETC), although I don't remember exactly which section it was, but it's a bit annoying that they come with the wrong shader by default and require modification.

This is one of my worries: whenever I use the Koikatsu studio for masturbation, I always end up using the same characters. I want to delete characters and scenes I don't normally use, but I keep thinking I might want to use them someday, so I can't bring myself to delete them.
Because of this, my PC's storage is getting really full.
Is there any way to deal with this?

Thanks for the confirmation! I don't mind adjusting the interpolables if it's this small. I didn't know about the reset to get the original position, thanks for that, now I don't have to manually adjust it haha.

I tried messing around with the shader and this somewhat worked. For some characters it worked a bit better but if one does not want to mess with the timeline, this could be a decent solution although it might look weird. Thanks for the advice, I will probably mess around with this more if I run into the issue again.

Store it in the cloud I guess if you really need more space on your actual PC.

You can have an external hard drive. It doesn't necessarily have to be in your Koikatsu game directory for a character or scene to be used. You can drag and drop a character or scene from your HDD when Koikatsu studio is open. The only exception is the mods. You have to have the mods in your game directory for it to be loaded, but characters cards and scenes can just be dropped in without the need of selecting it in game. It works just fine.

Character breasts behaving strangely after updating plugins. Not sure which plugin/settings is causing issues or if I'm missing something. In this scene the breasts are pressed together while in other scenes they move normally for a bit before flipping around wildly.

It's not my favorite way to work, but I'd recommend saving the content you want to archive in the cloud, whether it's Drive, Mega, or another cloud service. Just make sure it's not flagged content and that you know exactly who you're sharing it with (I hate cloud services because they're so easy to take down and they don't give you an ultimatum to download everything you have there; it's easy to lose content from them, but they're ideal if you're only using them as a private library in case you run out of space).

My actual solution, and the one I use, is hard drives. They're not fast, but they're cheap. I use 1TB drives, and I'm currently at 500GB, including my own content, content shared with me, and content downloaded from other platforms. However, losing those drives due to failure or overheating is entirely your responsibility.

Hi, how do I get my Koikatsu to look like the DOLLHOUSE's renders and style? I know the author uses KKUTS, but I'm not sure which settings to tweak to get it to look like how they do it. The DOLLHOUSE renders and style is something I really like, but I can't figure out what to do to make it look like it. They do share scenes and characters, but they never share the exact scene to make it look like their style.

The right image uses DOLLHOUSE Scene and DOLLHOUSE Character but it's nothing like the original on the left image

The attempt above is what I tried myself, but I can never get it to look anywhere near it. Frankly speaking, I'm completely lost on where to begin because KKUTS has so many sliders that I don't know what affects what. That's also in combination with character lighting and scene effects which is another process I'm not so sure how to tweak. Any help on this will be greatly appreciated.

or if there are any tutorials that I can just read and follow, I'll also be grateful for that.

or if there's a scene that perfectly replicates it, I'm also okay with that hahaha

How can I secure this accessory to the navel?

Ah yes, my old nemesis: the navel piercing. I tried for a while to get these specific types to work properly with animations and poses, but no luck.

The issue with this type of navel piercing is there is no parent that is the navel. It is always in relation to the parent. This is a problem because the novel moves in XYZ coordinates from the parent depending on the poses. This can be seen even in the simple bounce pose in Charamaker.

I'm no expert, any maybe someone knows better or can figure out a way to create a navel parent, but our options are thus: stay with this type of piercing and move it as need for static scenes and remove it for animations, or switch to one of the piercings that is static, like "Navel Piercing Heart & Sphere [ACP]" which is more like clothing and skinned to the navel.

Have you tried using AAAAAAAAAAAA and setting it to waist_01 or spine01 (both j_ and s_)?

Oh nice thank you! I didn't know sixpluswan made a KKUTS guide. I'll give it a try. Thanks again and I appreciate you taking the time and trying it out yourself!

EDIT:
If anyone knows if there are more KKUTS guides out there, I'd love to have them as well. Maybe if I have enough guides, I can mash the knowledge together then average it out to get the result I want.

[Helblind]

Yeah, I've tried a bunch of locations. The issue is there is no... I'm not sure what it is called... bone slider(?) right on the navel that moves with the navel. I can move them to on the navel but all the movement seems tied to the spine or the breasts or something else, all of which bounce and move differently than the navel. I'm not sure I am explaining it properly, but when the pose changes the parent location's relation to the navel changes in various ways, resulting in the piercing no longer being in the correct location or moving in time to the animation. I'm open to ideas, though!

Click on the character and go to the Material Editor for check if the head have the shader similar to the body.
If there's are different, put the same body shader to the head.

Thank you for your reply, they have the same shader

It only happens to me in that scene, when the character is inside an apartment (object, not map).

You‘re right,i know the “Navel Piercing Heart & Sphere [ACP]”, i just want the piercing like that, but i can’t . the "Navel Piercing Heart & Sphere [ACP]" seem have a special bone binding

Aight, I'm stuck. I have no idea what I'm doing, but I don't want to give up. I'm not sure what else to change. The guide that sixswanplus made at least taught me that there's something such as a Shader Management Tool to easily swap shaders. I previously doing it one by one so that's a plus in my book. But in the end, it made it look like sixswanplus instead of the DOLLHOUSE. 😅

With the chika sample that gustavo40 gave, I tried swapping it to the character and adjusting the settings. It's somewhat getting there, but now I'm stuck on what to change. Even tweaking some sliders in KKUTS don't do anything, so am I missing something with what I'm adjusting?

So I tried experimenting with scene effects and shadows, but it's not close to the color of the DOLLHOUSE anymore. Something about the scene makes the skin color so different to what I'm trying to achieve. Am I missing a normalmap, detailmask or something? Does it have something to do with the base scene settings or character lighting? So I'm basically stuck here.

And just to clarify, if it's grayed out, does that mean nothing happens or something?

I'll provide the scene and characters below with what I'm working with.

Hey guys,

My Charastudio is acting weird.
I try to hide some characters, clothes or acessories by clicking in the respective selection boxes, and they simply don't dissapear. Some characters do, others not.

In some scenes I save them with some acessories off, when I load them the acessories are back on again.

What's happening? It's some mod or plugin imcompatibility?

I believe what you should be messing around with is matcap. That's what gives the shine/glossy effect.

I don't use KKUTS so I don't have many lying around. I tried a few but they dont look much like the one dollhouse uses.

And just to clarify, if it's grayed out, does that mean nothing happens or something?

Also, grayed out just means it's not a default value.

Check if you're using either AccStateSync, AccessoryStates or ANAL. They are used to dynamically toggle accessories.

Duly noted. I haven't touched matcap at all, but given that you suggested it, I'll have to study it. I'll see what I can do once first before I have something to show again. Thanks dude for the info 🤝

No, don't hahah, those are very useful!

Sorry for not being more objective with my asnwer. I meant for you to figure out how they work and wich one might be causing the unwanted acc permanency. I'd wager it's AccStateSync - that is if you're using BR, i think it comes preinstalled with madevil plugins.

Only way I could think of replicating this was to diable the char's body/head/eye etc on ME. Would that perhaps be the issue?
