If you need your text engine to have bold text but don't want to get bold versions of all the letters then you can use this. You can use this with clones Hold space to make them move and change color (Only to demonstrate how smoothly this engine can run)
Note: Less laggy if the text doesn't move The text may look weird but that is because to demonstrate that this can handle 300 clones I stacked 60 clones on each B (click see inside and you can test it)
