Turning the rich text option on a textbox inside a billboardgui makes it act strange, almost as if its reversed compared to normal textboxes inside billboardguis (normally, you get up close to see the text bigger, but in this case it’s the other way around)
The text is actually staying the exact same size… in screen space, in pixels. You expected the billboard gui to stay the same size in world space, i.e. shrink or grow on the screen as you move farther or closer to it.
This is probably a bug, can someone else voice their opinion on this as well?
If you really, really need a RichText on a BillboardGui, you can make a script manually resize the textbox according to the distance from the camera (on a loop).
I looked at the thread regarding the launch of RichText, which was back in july and I noticed somebody saying TextScaled was still a WIP and not working. Sadly, that seems to still be the case. I wanted it for the italics and to color parts of the string but it seems it’s too much of a hassle.
