Ohhhh thats really cool, will definitely use this for something ive been struggling to think of how to add

travh98.bsky.social•156 days ago

This is huge, thanks!

richbuilds.bsky.social•156 days ago

Another one to add to the toolbox - thanks for sharing :)

I notice it doesn't scale though with distance.

If you need that, use a Sprite3D with billboard enabled and a viewport texture containing the control.

stayathomedev.bsky.social•156 days ago

True.

You could scale manually or set a default size and maintain it.

Looks like the same could be achieved with Label3D that has a "fixed_size" flag set to "true", no?

stayathomedev.bsky.social•156 days ago

For text absolutely. This allows Control node use as well...so full UI support.

wchc.pl•156 days ago

Ahh, I get it now. Indeed for Control nodes other than Label3D that might be super useful, didn't think of that.
Thanks for the tip!

You'd have to set the billboard flag as well, I guess.
unproject_position3d has many other uses, though, mainly when you want to connect a 3d object with (normal) UI nodes.

wchc.pl•156 days ago

Yup, I get it now. For other Control node types it might be super useful. Thanks!
