Title: Billboard rotation
Post by: K24A3 on January 30, 2012, 01:11:12 pm

Is there a way to rotate a billboarded Object3D on it's Z Axis?

I have a textured plane that has billboarding enabled and would like to rotate it clockwise as if you were looking at a fan spinning from the front.

That's not possible, i'm afraid. The billboading replaces the rotation matrix with an inverted camera matrix. So all other rotations are lost. If you want a different behaviour, you might want to set the rotation matrix yourself.

Will do, thanks.
