I modeled a bottle and decided to texture it with mental ray, I used two mia_material_x, one with solidglass presets and the other with glossyplastic (for this one I add a file img that represent the "label" of the bottle), the whole arranged in a layered texture shade with some option. But when I render this with my mental ray (render settings under Production quality) my blue writing and the blue neck of the bottle turn into yellow for some reasons that I can't find !
(I added images for more precision) I hope you guys can help me !
