I have several objects in a scene that I would like to animate a material (text) (image map) across them all at once going right to left. Any ideas how I could do this?

Never tried it and may be a version dependant feature but there is a projected animated texture node that can be used to project a texture map across several objects using world coordinates. The thought is add an alpha blended layer with this node set-up to the desired objects and animate the UV offset - just an idea, no idea how feasible.

Thanks for your reply. I will see what I can do. I'm not super familiar with using nodes but perhaps I can figure it out. Thanks.
