objects in render, keep turning purple

i have been using SUfVray for a while now- but have not had the chance to use my renders for work! i have final followed a model through to the final stages and all of a sudden, certain objects (after already creating white) have gone purple- i have exploded and regrouped, reversed faces and reapplied materials and have turned them into vray linked-even though they are white. does anyone know what i can do about this? as usual, i dont have much time.
help! lol

Re: objects in render, keep turning purple

i’ve got a same problem in some of my images. As i know when your surface of the model is not normal face. i mean the front and the back face. if the surface is back face. that’s would be coming up purple colour. But sometime when the glass reflect some of the suface become purple as well ..no matter it’s front face or back face. and i have no idea what’s that happen.
You may try to reverse the face and see.
