I need to get an object to always face the camera. I've seen this used
for trees in a background where a tree texture map was applied to a
planar object and then an expression was written to keep the planar
object always facing the camera, so one couldn't tell that the trees
were just flat texture maps.
I've gone through the manuals, and I've figured out how to get an object
to spin or translate based on a camera's attribute, but I can't figure
out how to get the object to stay put and face the camera as the camera
moves through the scene.
Any help or suggestions would be appreciated
