Just some experimentation. Really, I started randomly pressing buttons like a monkey - rendering each time.

Note that the material will be visible in reflections and refractions.

Right, so in a window you would see the reflection of that green cartoon tree.

what about the checkbox right below that one? (Exclude All Materials from Reflection/Refraction)

@AcesHigh

indeed, the exclude materials checkbox works pretty well. First image
original

Here is the option of visible only in secondary for the tree material
tree material hidden

The mirror material has the exclude materials from relfection/ refrac. option checked (optimize exclusion didn't seem to make any difference)
invisible

Hello,

I have v-ray to Sketch-up 7,
I can´t find the option "only visible in secondary"
in the material editor. Could it be I have an old version?

What version do you have? Latest is 1.49.x

The problem with exclude object form the reflection is that you will exclude all the object.
