Why are 'appe', 'loca', 'pose', and 'uv' generated only when rendering is enabled?

[daviduarte]

The features 'pose' and 'appe' are mandatory for the pretrained checkpoints of the LART method, but these features are only generated when self.cfg.render.enable=True. However, I just want to generate the features for my dataset, not render the images. Is there a way to disable the rendering but enable the generation of these features?
