Grass tracking to camera

I’m using planes for ‘3D’ grass in the game engine, and I can’t figure out how to have the grass plane track to the camera, while only rotating on the z axis. Any ideas?

Select ‘billboard’ under the face panel. You also have to rotate the plane in such a way that it is facing the camera. Screenshots coming up soon!

That’s a good way to show it. I would recommend a highlight colour other than black, though.

Is there a difference between using “Halo” and “Billboard”?

I always used Halo for vegitation and particle effects.

Halo causes the face to track to the camera indiscriminately. Billboard forces it to remain vertical. Very much like the difference between 2D and 3D tracking.

Ahh, I see.

Thanks Toomai.
