Segmentation annotation about controlnet-v1-1-nightly HOT 2 CLOSED

I also wonder how to prepare annotation for training CNet segmentation. Your great guide showed custom dataset prepare regarding very simple case, but Segmentation must involve much more sophisticated processes. Can you guide me in more detail?
for example, in your guide, you showed a example of circle images.
If there is one circle and one star in the image, should I make segmentation GT map(is it needed?) like a circle filled with red color and blue color for the star and black color for the background.

Regarding segmentation class id map(e.g., in COCO format), I would set class id 0 for background, and 1 for the red circle and 2 for the blue star.

But are those class ids needed? Maybe no? and just I need to make prompt "vivid red circle and blue star with black background"?

Thank you!
