Koikatsu Character Importing Guide

Learning how to handle koikatsu character importing correctly lets you skip manual slider adjustments and bring custom creations straight into your game. If you've ever downloaded a character card only to find it missing textures, showing up blank, or failing to register entirely, you're not alone. Most setup issues stem from incorrect file directories, stripped metadata, or missing mod dependencies rather than a broken game install.

Getting custom cards to work requires understanding how the game reads embedded PNG data and how to manage your local asset directories. This breakdown covers everything you need to move, verify, and load character files seamlessly.

Understanding Koikatsu Character Cards

Koikatsu stores all character appearance data inside standard PNG image files. These aren't regular pictures you view in a standard photo gallery; they act as containers holding numeric slider values, hair parameters, clothing selections, and color palettes.

When you download a card from community repositories like Pixiv or dedicated fan forums, your web browser must save the full-resolution file. Saving a compressed thumbnail or screenshot strips out the hidden metadata chunk at the end of the file, rendering the card useless.

Verifying File Integrity Before Installation

If a newly downloaded card refuses to appear in your game browser, you can quickly check if it contains actual character data.

1. Locate the downloaded PNG file on your computer.
2. Right-click the file, select Open with, and choose Notepad or any basic text editor.
3. Press Ctrl + F to open the search bar and look for strings like koika or sex (referring to the internal data flags).
4. If the editor displays lines of code mixed with unreadable symbols, the card holds valid character data. If it only shows standard image header text or fails to open with readable binary blocks, the image is a flat screenshot.

Step-by-Step Character Import Process

Moving files into the correct directory ensures the game's internal file scanner detects them instantly upon launch.

1. Navigate to your main Koikatsu installation directory (commonly found inside your default Steam or custom modded build folders).
2. Open the folder path UserData/chara/female for female character models, or UserData/chara/male if you're importing custom male presets.
3. Drop your verified .png character cards directly into this subfolder. Avoid nesting them too deep inside extra sub-folders unless you use an organized cataloging tool, as deep nesting can slow down load times.
4. Launch Koikatsu and open the Character Maker suite.
5. Click on the Load menu option. The interface will scan your chara directory and display all newly added cards as selectable thumbnails.
6. Select your imported character to populate them into the workspace.

Troubleshooting Missing Assets and Mod Dependencies

A common frustration during koikatsu character importing happens when a loaded model appears with gray skin, distorted hair, or missing clothing items. This occurs because the card relies on custom mods (such as sideloader mods or specific hair/clothing asset bundles) that aren't present in your current installation.

To resolve missing asset errors, ensure you maintain an updated mod environment using community-standard patches like the HF Patch, which manages required BepInEx plugins and dependency frameworks. When a card fails to map correctly, check the BepInEx console log generated during startup to identify exact missing texture paths or outdated shader plugins. Once you install the missing mod dependencies, reload the character maker, and the model will render as intended by its creator.

Frequently Asked Questions

Why does my imported character look deformed or stretched?

This usually happens when a card was built using body adjustment plugins (like ABMX) that alter skeletal limits beyond the vanilla game's default parameters. Installing the corresponding bone-mod plugins fixes structural distortion.

Can I import characters from Koikatsu Sunshine into the original game?

No. Character cards created in Koikatsu Sunshine utilize a different internal data structure and updated asset skeletons, making them mutually incompatible with the original Koikatsu Party engine without manual conversion tools.

Where should I store cards if I want to use them in Studio mode?

Character cards used in CharaStudio follow the exact same rule. Place them in the standard UserData/chara directory so the Studio sidebar can access them when spawning background entities or custom scenes.

Why does the game freeze when I open my character folder?

Having hundreds of loose PNG files directly in a single folder causes lag during directory indexing. Create well-named sub-categories inside the chara folder to keep load times fast and file management organized.
