Un T-posing a 3D model refers to the process of changing the model’s pose from the default T-shape to a more natural or customized pose. T-posing is a common starting point for 3D models, as it simplifies the animation process by providing a neutral and symmetrical pose.
There are several reasons why you might want to un T-pose a 3D model. For example, you may want to create a more realistic or dynamic pose for your model, or you may need to conform the model to a specific environment or animation sequence. Additionally, un T-posing can be necessary for certain types of 3D printing or rendering.
