It just shows the little lines pointing to where the labels should be. I've tried it without any other mods other than Carpet and Fabric API but it still doesn't work.

The scarpet shapes label renderer seems to be broken

For example, create a label shape with command /script run draw_shape('label', 100, ['pos', [x,y,z], 'text', 'fooobar']), nothing will appear (reproduced with 1.21-1.4.147+v240613)

and the size field of “label” is a float, but it is using a PositiveIntParam.

One of my projects requires exact text size and I'm running into a problem here.

i think that i have fixed this problem.

wait. looks like there is still some issues...
