Tell us what got stuck, a bug, or a feature you want. It goes straight to the developer.
For bugs, please include the mod you are using (name, version, where you got it), the model type (PMX, glTF…) and the steps that cause it. It makes the cause much easier to find.
Model and mod files are never sent. Only what you write, the info you tick and any images you attach go to the developer. Please check that images show no personal information.
