Glass Noise Problem

Hi,

Does anybody have any idea about this glass material problem, they are not overlapping and the glass is a simple glass material. My object is a sliding door and noise appears only in multiply glass objects?! 



Thanks!

Have you try increasing you max depth material setting , Sir?
Check mo  din and object normal ng mga objects baka my problem.
Kalimitan ang noise galing din sa material subdivs and lighting subdivs.
Try experimenting those setting.
Hope I could help.

Thank you nobomic it helped a lot!
