Hey GEN and DAVE,

Thanks for you interest and comments so far. So I decided to open the project on another system, re-create my shaders and now it all works. The settings seem to be the same across the board, but one yields good results and the other, not so good.

It's strange, I applied a temp texture to a blinn, and before it was even tiling that, now this time, it's perfect. So I applied the diffuse pass to the violin using a blinn and that now worked too. Then I applied that to a mia_material_x and slowly added the glossy and reflection passes and they all worked too.

Again, not sure why one system works and the other doesn't, but thanks again for both of your interests in my UV conundrum.

Cheers
