bump map symmetry

[i777]

I have imported a model of a car where the headlight lens has been modelled and then symmetry applied to the layer. Obviously in Keyshot it shows as 2 lens - one either side.
I have applied a bump map to the lens material (glass) and then used box map tool to line it up with the right side lens. It looks good - so was then fully expecting the opposite side
to have the matching effect....except that the bump hasn't worked/applied to the other side - it just has the glass material and no bump texture.
Can anyone offer some advice? - am I missing something obvious?

Thanks for any help.

It's kinda hard to picture what you are talking about, but
A: make sure they are linked or the same material.
B: check your repeat option, otherwise you may only get a defined square of texture and thats it.
Let me know if that helps

Copy / paste the material? Have you tried that? Shift left click onto the material, and then shift right click onto the target part. This will copy, paste, and link the material on those 2 parts.
