Problem with subcomponents’ origin when applying texture

[ianhardies]

I wonder if anyone can help
I have a component made out of several subcomponents.
These Subcomponents are dynamically stacked one on top of another and when I apply a texture to the overall component, it gets applied to each subcomponent at its origin.
Is there a way to apply the texture to the entire component at its origin?
I’ve noticed that if I have all subcomponents share the same origin as the overall component the texture lines up correctly. How can I dynamically change each subcomponents origin?
Thanks for your help
