Thank you! yeah, I know the dialogs are broken, I made it with sprite of a dialog and textmeshpro, do you know how to make it better? If you do, I'll be very thankful)))
You can rotate the parent object (containing sprite + text) facing camera with:
// target is Camera transform
transform.LookAt(target);
Hope it helps :)
Yeah, I've tried it, the text still wasn't visible))) but I think it's because of my water shader
