    Default Glass Material Noise Problem

    Hi,

    Have you ever had this problem with a multiply objects with a glass material, they are not overlapping and the material is a simple glass.

    Thanks,

    Is this in vray and 3dsmax?

    if so - Right click on the glass and select V-ray properties and uncheck visible to GI.

    In render elements add VrayReflection, VrayRefraction, VrayLighting, and VraySampleRate.

    Use the vray frame buffer to switch between these elements to determine where the noise is coming from. For reflection noise increase reflection subdivisions in the material - same for refraction. If it is in the light increase the subdivisions in your light.

    This is pretty general. Hope it helps.

    Thank you RendNerd!

    Yes it is 3dsmax and v-ray, sorry for not mentioning it! I fixed it by increacing the Max depth of both the Reflection and Refraction, but your explanation is very useful for me. I never thought this way before for checking subjectively the parameters that way! Thank you!

    Kind Regards,
