error msg

i was using a ray traced material that is supposed to be a glass, meaning its transparent and somewhat reflective. rendering with vray i got an error message that reads:

warning: Material returned overbright or invalid color (object…)

what can i do about this. i want to use glass like materials. I am using the free version of v-ray.

thanks,

raytraced materials dont work with vray, either use a vray material or a standard material with the the “vray map”
