Hi,
You wouldn’t happen to have an example for your needs?
Labels should be attached to meshes (and should you interact with them?)
There’s recently been a number of topics around this subject in the forum. Choices are basically around using a dynamicTexture, cloning GUI for mesh or using a shader. I think you can exclude the meshwritter (my opinion).
Here a few links that might be of interest to you:
To get better advise, I would really recom you give some more information (or create a small PG).
Meanwhile, have a great day
