I’m using 4.0 and have a Sprite3D. It dutifully moves with the camera, but not in the way described. It always faces the local axis of the camera instead of the camera itself. So if the camera happens to be looking directly at it, then it does face the camera. But if the camera is facing elsewhere, then so is the sprite.
In other words, I get this:
. \
---S--- ---S--- S
| | / \
| | \ /
---C--- ---C--- C
\
instead of this:
. \ \
---S--- S S
| / \ / \
| | \ /
---C--- ---C--- C
/
Anybody know if there’s a way to change it to the latter without manually managing it?
