Is it possible to copy the underlying UV mapping from one object to another? I am NOT talking about texture mapping with the materials editor or editing emissive textures.

 

Example:

 

Two ELS lens objects using the same texture with a blue lens and red lens. For the purpose of this example, on the texture the blue lens and red lens are different sizes/shapes.

 

One object is mapped over the red lens. The other is mapped over the blue lens. I would like to have 2 blue lenses.

 

Is there a quick and dirty way to copy/overwrite the red lens mapping? I want to save myself from either editing the existing mapping or generating a new one.

 

Thanks!

If I understand correctly, you want to remap the red one to blue? Try this:

 

Surface>Mapping>Edit UV then proceed by clicking the object. A box should pop up and tick "generate new". Change your viewport to UV Mapper, then go to the bottom of the viewport and click "materials". A list should pop up and select the desired texture you want to remap, the object should be shown in that viewport. Proceed to scale, edit move and such within the viewport. 

"Proceed to scale, edit move and such within the viewport."

 

I am trying to avoid the tedium and skip this process. My question is if there is a quick and dirty method, which might not exist.

You could edit the light texture to change it, that's another way that doesn't take long at all. Copy the blue light texture and paste it on top of the red one.
