Glass material and losing small geo

[AbeMata]

Hello,

Something is going on here that is escaping me. I am rendering some very small pieces of geo, motherboard components and connectors etc. The even smaller geo seems to dissapear in the render, and doesn't even show up in a normals pass. This seems to be a matter of scale. Any ideas would be very helpful. Thanks!

Okay, problem solved. I had a plane intersecting the geo right above those small parts.

Sheesh, just one of those days I guess.
