problem material script

[3di]

Can anyone provide a script which can search for materials that have reflections enabled and no rayswitcher child node on the reflection colour slot?  I've got thousands of materials in a huge scene, and a couple (that I can't find) are causing fireflies :(

You can try decreasing MSI (Max Sample Intensity) in render settings. Just don't go too extreme. I would suggest checking values like 10, 5, 2 and seeing if it does not affect the rest of the scene too much.
