[ILLUSION] Koikatu! - Questions & General Discussion Thread

[White_Runner]

One more thing to check. Is everything all right here? Is there anything unusual about the numbers? Except fps due to the mod

https://files.catbox.moe/arniyu.png

Something something in that object is making your GPU go brr.
The RTX 5060 isnt that bad of a card either, I could run Stalker:Gamma on the RTX3060ti at 3440x1440 and that one is older...

This is weird... (Take a look, it went from 54% to 99%):

Either the object is having yandere sim brush levels of topology...

Or something isnt right with the material editor configura... woah the amount of different objects inside is impressive...
This could be normal, I mean Ive seen worse... Here is one for each rope...

Oh shit... why is it using KKUTS_Tess... also... WHERE... I dont see tesselation... so... WHERE...?

Ok, the DoNotEdit object is applying tesselation to something something... let me take a look...
Ok, the normal amount of tesselation for non tesselated characters is 5... this is 2... so this object is tesselated.
(By default when you apply tesselation this comes with 5 TessEdgeLength, when I add tesselation to an object I reduce it to 2...
[It allows even less but the roundness improvements are insignificant...]

Bruh, are these tesselated pads...??? First time on my life Ive seen them.
See, if I increase the extrusion, the pads go bigger, if I lower the extrusion, they go smaller...

---
Ok, this might take a while to explain so:
The same way this universe is made out of strings (See (S)tring theory, the cosmic (S)erpent, (S)atan, a line in a piece of paper, the writting (S)ystem, etc)... [Yeah, all lines on this reality are Serpents]...
All the 3d objects you see on your computer are made out of triangles.

Why? Because is the easiest way we found out to represent 3D objects in computers.
See this cool dolphin, is made out of lines, triangles!

(I mean you can use rectangles too, but triangles is where the good stuff is)

But triangles can only represent detail up to some level.
Titties, feet, ass, the good stuff IS ROUND!!!
So, what is "round"? Round is complexity, round is infinite!
(In reality all the stuff you see are infinites, the circuits on your processor have the complexity of a city.)

And so, the NUMBER OF POLIGONS IN A CIRCLE IS INFINITE (Banarch Tarsky Paradox):

Thats why the default ass and feet you see on vanilla koikatsu is not round. Its because the models have a finite number of triangles.
So the level of details is FINITE. So, how do we improve the "roundness" of an object to simmulate infinity even if it isnt infinite?
I want rounder titties, better feet, an spicier ass!!! : Tesselation.

Tesselation is basically appliying divisions to the lines of the triangles, therefore, you get more triangles out of the same original triangle!

---

What was happening is... that the autor added FAKE TESSELATED TITTIES (PADS) inside the rope object:

If your gpu isnt that potent, they might decrease your fps.
But its weird, Ive applied tesselation to multiple objects on my old 3060ti and the fps decrease wasnt that big.

So I suspect that 3 things are happening that lag your system when you apply the rope object:
1) Your KKUTS shader isnt up to date. UPDATE IT.
I mean, you know about bugs, optimization and stuff.
If its lagging so much using KKUTS maybe its because the version you use of KKUTS isnt up to date. So Ill advice to update it:
https://www.pixiv.net/en/artworks/131615852 (KKUTS 2.5.1)
Damn, new version I must update too...

2) If you are not going to be using tesselation, disable the tesselated PADS.
To disable tesselation in this case, Ill change the renderer from KKUTS_Tess to KKUTS since both are compatible with each other.
Tesselation will be disabled.

3) F1 -> Plugin settings -> Graphic settings
(4x MSAA is my preferred method but you can live with 2x or 0x, also Ill always force anisotropic filtering since fps decrease is insignificant.)

You can also try installing ReShade shaders if you want to experiment using FXAA or other sharpening methods.

Discuss features or the changelog of the latest ReShade version.

Remember that reshade uses GPU not, CPU to alise borders.

(Yeah, learned that applying FXAA to stalker Gamma (cpu limited to 1) and Helldivers 2 (only has FXAA support))

Hope this tesselation class helped you fix the issue!

Something something in that object is making your GPU go brr.

I updated KKUTS just now, thanks. However, initially there is no such KKUTS setting on the rope or chara, it is possible in your uploaded chara. But I understood the main point, there are a lot of polygons on this rope, and my PC can't handle them. I've tried playing around with shaders, but it seems to have no Effect

https://files.catbox.moe/ecxwn4.png

 

[Eudoxus]

I guess I'm just stupid or completely missing something

So what it says to do, in order:
1. Go to Body tab
2. General
3. Set Skin type to 11-Light 1
4. Open Material Editor
5. In cf_m_body, set Texture2 and Texture3 ScaleX and ScaleY to 0.28
5.1 Copy edits
6. Go to Uniform tab
7. Legwear
8. Open Material Editor
9. Find m_thigh
10. Paste edits

What am I missing?

Just in case, check if you have duplicated mods
Had to delete some mods because, even if they had different names they have an "internal uid" saying:
"Hey im the same mod as that one, choose me"!
And it may bug stuff... I dont know, it might work... I gained like 30 fps doing that...

To do so, use the koikatsu console. When I opened it and loaded the bra, it said that I had duplicated stuff.

Given how inexpensive it is to create blendshapes with BlendShapesCreator or use low-poly models with a standard map, I think you can save yourself the tessellation.
Which isn't bad, but I prefer to apply it to bodies with DisplaceTex, not clothing.

Something I'd like to add to your explanation is that the zipmods created with the Unity project, which you can download from GitHub, package the mod with "[name]" at the beginning.

This can give the [A-fan] version a certain priority over its version without brackets, even if it's the same content.

It's also worth reading the manifest, because there are zipmods, like those for Evaan, that have the same name but are different versions. Similarly, the Naruto mod has about four versions with different content, but they're all called "[Evaan] naruto_gurls_mod," and putting them in the same folder will overwrite existing files.

Hi
Does anyone know how to fix this error? It makes the scenes lack lighting and appear very dark



I downloaded this version https://dl.betterrepack.com/public/#list-koikatsu

I haven't installed anything on it; I just started using it as soon as I downloaded it.

Nope, it's the same. Still, I think it's my 5060, it won't be able to withstand many polygons like this rope. But anyway, thanks for all the help, I've never met such honorable people, I'm very glad

Honorable...? Me..?

As I said, I played with tesselation on a 3060ti which is 8% slower than the 5060.
In no way your graphics card is slower.

Final take would be to update all the mods you can

If that doesnt work, dont forget about this ones:
BepInEx
BepisPlugins
ShalltyUtils
HSPlugins
IllusionModdingAPI
Timeline (this one is optional I guess???)

And update Nvidia:
1) Update your Nvidia drivers.
2) Then, go to 3D config, then program config and allocate maximum performance on Koikatsu.exe / Chara Studio.

Idk why, but it seems that the Nvidia settings do not affect the game at all, as if the 5060 does not perceive the game

You have to manually locate the game in the nvidia control panel.
Forget about nvidia app, that one doesnt work.

Does anyone know how MightyMeat is able to keep the same uncensor pussy in his scenes? for example if the base character in the scene in has SAC Kupaa, but the character you change it with has BP Clit, it'll change the new characters uncensor pussy to SAC Kupaa.

I want to know this trick because several creators use blendshapes and require their version to use a specific uncensor pussy, and if you change it b4 blendshape has taken place (i.e. in the beginning of the scene) you mess it all up and have to reopen the scene

Maintain the uncensor after changing character?

That doesnt work.

What I do is take note of the uncensor used by the creator.
Then, after replacing the character I change the uncensor.
The uncensor in this moment will be bugged.
Solution?
Save the scene and reload it.
That would fix the issue.

just wondering what mightymeat does to make it so it's always that specific uncensor he would use in that scene when changing characters.

only select clothing and overlay checkboxes at the bottom when loading. if the thing uses accessories, you'll have to check the accessories check box, then copy the hair accessories from another clothing tab.

Is it possible to learn what mods use a card? I want to delete some cards and mods to them, but I can't understand which mods I have to delete.

 

[theenemy333]

For a studio scene with a lot of characters such as this scene, what is the typical bottleneck for framerate? Is it mostly vram demanding, or high cpu demand, something else?

I've also been noticing chara studio has gotten slower overall (as in all scenes run slower, even basic ones) for me after installing the HF Patch including the scene I linked, but that scene was already running slow even before hf patch (difference of like 25 fps to 15 fps).

I've been thinking of upgrading my PC (AMD Ryzen 9 5900, RTX 3080, 64 GB RAM, Win 11) to improve chara studio performance and improve overall speed with HF patch (I also notice the card maker in the main game runs at a lower FPS with HF patch) but I'm not sure what I should be focusing on.

Should I get a GPU with significantly more vram or a just upgrade to an overall more powerful card with about the same amount of VRAM or maybe the CPU is where my bottleneck is?

Is it possible to learn what mods use a card? I want to delete some cards and mods to them, but I can't understand which mods I have to delete.

I would use KKManager, it works for both cards and coordinates.

On KKManager 1.5 it works like this:

1) Copy paste the directory of the cards/coordinate you want to check.
2) Click on them.
3) Open: Extended Data(plugins)/com.bepis.sideloader.universalautoresolver/RequiredZipmodsGUID´s
There you will find a list of the mods you might need.

Tho I believe this method might have changed in the latest version which you can download here:

Idk if such a question has been asked, but is it possible to improve the quality of the mirrors in the game? Is there a mod/plugin? Or is it possible in the game itself?

It deppends on your approach to mirrors.
You could use a mirror object or use a camera that works as a mirror. (fancier)

Or as WamekuKyouzin (kk discord) said:
Note: How to get better mirror resolution:

1. Open RuntimeUnityEditor (Ctrl+R) and display ObjectBrowser.
2. Search for Mirror.
3. Select mo_koi_mirror and click mirrorReflection>Send to Inspector
4. Change m_texturesize.

This method is not saved in the scene, so you must do it every time you load it:

Koikatsu its not GPU demanding.
Koikatsu Its not CPU demanding.
Its even worse.
Koikatsu is "Core 0" demanding.

"...Core 0"?
Your CPU (Central Processing Unit) is made out of different cores inside it.
Why? -> Because its optimal. Having only one faster core doing stuff became inviable because of physical and logical limits.
Therefore, manufacturers started increasing the number of cores inside a CPU.

Why have an overworked person doing stuff when you can have multiple clones of said person doing said stuff in paralel?
The more clones, the more stuff you can do. Thus, multicore cpu´s were born:

In my case the 5700x3d I have as CPU has 8 cores, 16 threads which are like 8 people with 2 hands each doing stuff for me:

Each core is assigned to a task it must complete before starting another task. The more cores the more tasks you can do.

So, whats happening with Koikatsu?
-> The version of Unity (Koikatsu´s engine) running (5.6.2) its not designed to run stuff in parallel nor have good multithread support.
-> All the workload (physics, blendshapes, IK, meshes, accesories moving) is done by only one core.
->As such, even if you have 6 fps, the CPU usage will be at maximum 25%:

CPU: Unused

<-This with Koikatsu ON gives 10 fps.
GPU: Not essential, but helps.

<- Withouth any frame gen.

<-60% of a RTX5070ti since im using smooth motion frame 2X, with lossless scaling 4x is even less.
A 3070ti would be enought I guess?

Why?
-> Real multithread support was enabled for Unity from 2020 onwards, Koikatsu launched on 2017, its development started way earlier:

Thus, Koikatsu its not optimized. What does it mean?
->Koikatsu will never use all the processing power of your CPU. It will allways assign all of the workload to 1 core even if you have 4,6,16, 64 cores.
Thus, even if you have a supercomputer, Koikatsu will be tied to the max speed of core 0 and maybe core 1 and 2.

->GPU is not the bottleneck, so the resources allocated to the GPU are free, which means:
You can use Lossless scaling (6x) frame generation or enable nvidia´s Smooth motion frame (2x) to do frame generation for you

Yes, they increase latency, but who needs fast reactions on a porn game?

You can have programs like ReShade which inject effects and use only your graphics card to enable extra effects withouth a big penalty:

What can we do then?
The chance of Koikatsu 2 (with all the optimization, raytracing, dlss,whatever) releasing is really slim.
After all, Illusion closed on 2023 and Illgames is not its official successor.
Thus the only way is to optimize the scene.

How?
Well, the biggest culprit of low fps on scenes is actually... the accessories you have on each character.
Why? Because they move. And there is only one thread calculating how each accesory moves.
Therefore, it lags like hell.

Solution:
-Disable gravity on accesories and clothes.
-Work with characters with less clothes or less accesories.
-Check how much fps maps take from you. Some maps are fps hogs.
-Use the video capture mod to create videos (It renders the image frame by frame and then glues all of them together lmao) which takes a while but works.
-Learn about Graphic settings.
---
Life and death are decreted by fate. Prosperity is up to heaven...
Im going to be honest with you, if Koikatsu launched on 2026 it would have probably been done on Unreal Engine 5.
It wouldve come out with lumen, raytracing, DLSS, and need 64 gbs of RAM and multi frame gen to run... and so it would suffer of success.
Because nobody would be able to launch it.

So... maybe the current state of the game is a blessing on disguice.

That might be a loading bug.
