Material IDs and lens effects

[c2phace]

Hello,
I've been researching this all morning and cannot find any direction. Maybe it's not possible.
Vray for Sketchup offers lens effects, but some of the properties (bloom masks, glare masks) require a Material ID. The problem is that this is an integer and not a color. I cannot figure out where to set this for the material. Also it seems like the "intensity" option under the masks do not work. I'm trying to set the glare effect to only work on certain emissive, and not others.

I know adding this in post is possible in alternate software, and I can achieve those effects, but I'm trying to see if it's possible with vray's lens effects.

Any ideas would be great!

Note: The service pack 3 for vray was released and states this under bug fixes "Altered how the Material ID and Node ID render channels work, they should have been integer channels instead of color." I have this service pack, and cannot figure out how to set the integer.
