Hi,

How do you rig an eye so you can just animate the texture with a control dummy or bones or something so you don't have to create a round sphere with a lookat constraint?
I've seen game developers do this since they are always limited to low poly count.

Can anyone share this technique? Thanks :)

My first guess would be, to use the texture coordinates. Your diffuse map channel in the material editor has UV - Offset and angles. You could wire them to the rotation values of a dummy object. However, you should think about your UV - Layout. Since these offsets manipulate the position of the texture in UV space, you may run into problems like distortion, depending on your UVW Map and Unwrap UVW.

I'll go and try to do a wire parameter on the UV offset of the texture material

But would it be great if we can contol a Planar UVW Gizmo and just link it to a bone or to a control dummy? it would cetainly get rid of the stretching on the edges of the eyeballs. I did try and wire the Planar Gizmo and all I was able to achieve was control the Left/right/up/down motion and not the rotation ... so it still resulted in some stretching.

Thanks .. I'll give your technique a try :)

Wire the gizmo to a dummy, align the dummy to the eye and use a look-at constraint for that dummy.
