PMX Editor is a powerful tool for creating and editing 3D models. One of the most important features of PMX Editor is the ability to delete material parts without deleting morphs. This can be very useful when you want to edit a model’s materials without losing the morphs that you have created.
To delete a material part without deleting the morphs, simply select the material part in the Material List and click the “Delete” button. The material part will be deleted, but the morphs that are associated with that material part will remain intact.
