looking at the BillboardEffect class:
BillboardEffect::make(LVector3f const &up_vector, bool eye_relative, bool axial_rotate, float offset, NodePath const &look_at, LPoint3f const &look_at_point);
Can somebody provide a description of the various parameters?
Also, is it possible to this effect to keep an object’s y-axis (forward) strictly pointing toward another object while it z-axis (up) loosely rotates to face the camera as much as possible?
Thanks for your help!
