idk if this count as a bug but it seems this revamp thing reset the characters model too the expansion mechanic on 3d model just won't work as if there's none in a first place
Just an oversight. Since the project is now hosted on Github, I didn't include any NSFW content to start. I'll put the old model back into the itch build only next time. However, the mechanics are still there. You can either add the old model to the game yourself via the 'Add VRM' seen during character customization or create a VRM model with the body shapes you want yourself. Nothing in code has disabled this.
The old model is now in the web version.
