You have created the UV mapping on Low polys. Converting the geometry from from poly to SubD has chnaged to layout of the UV's therefore changing the mapping and the look of the model. Chis, since you're a "Lead" modeller, you must be fairly knowledgable on my current problem. :shakehead Your quoted statement suggest my workflow is incorrect. After you complete a model, how do you go about "Bump" mapping it/rendering it? Curious Fess
