Billboard without Update loop

Im looking for a billboard effect that does not require calculating the transform on every frame.

Ive heard that parenting the gameObject to the camera achieves this, but then the objects move with the camera instead of staying in place.

Any ideas on how to achieve this? Or is it impossible?

You could use a Coroutine and do a check every other frame or as often as you'd like (every 5 frames, etc), or for example, when the camera changes position/rotation.

You can do that in the shader, actually.

@equalsequals could you point me to a resource on that? Thanks,

I'm not quite sure if this would work out but particle systems work with a billboard effect. $$anonymous$$aybe you can get what you want if you set the system up to have exactly one particle which is persistent at the position of the transform.
