Koikatsu to Blender to Unity to VRM Virtual Youtuber 3D anime model Koikatu コイカツ

Extracting 3D characters from Koikatu H-game using BepInEx mod and PmxExport.dll to export PMX model to Blender for Cats Blender fix then generating FBX model to Unity3d then converting to VRM model for Vtuber application. This video is a brief overview of the procedure and showing you the possibility of ripping models from Koikatsu for VRM virtual youtuber purposes, or for any other purposes like; for using the 3D character models generated from game’s avatar creator for use in Blender to work on.

An elaborate process of conversion from Koikatu model to ultimately VRM models. For VRCHAT you only need the FBX model in Unity and uploading through Unity with the use of VRCHAT SDK module package installed. No need to convert to FBX to VRM using UniVRM.

I’ve never used VRCHAT before as I don’t have VR equipment yet to try it out. Cats Blender was made to ease the character model transition from Blender to Unity for avatar creation to VRCHAT.

This vtuber was purely presented via a VRM model in a vtuber app.

Transitioning models from Blender to Unity and making a usable VRM model for vtubing. This takes time, trial & error, and experimenting. It’s not a complete smooth sail process. It requires some basic Blender skills, basic knowledge of general 3D character models structure (mesh, bones, material, blendshapes, shading, texture, plus eye tracking and visemes) and knowing enough about Unity to convert anime character brought in from Cat’s Blender. Basic Photoshop skills, etc.

Note
This same extracting process can also be done on V-Katsu.
