Fire flies

Why am I getting fire flies in my rendering. I fixed the white specs on the stone material but I’m still getting over exposed pixels on my glass.

Figured out the issue. When I add vrayedgetex into bump slot I get the fire flies on the orange glass fins. When I remove it, renders fine. Oh well.

It could be caused by the geometry, this looks like imported from a CAD software. Anyway you shouldn’t have fireflies - can you send me the scene?

It was created in Skp and imported into MAX. File is huge will send after deadline.
