Using a cube as an instance object, and setting the cubes visibility for primary rays off, it works as expected :-) the setting on the actual cloud is not effective when using instances, so it has to be on the original cube itself

Just out of curiosity, can you tell whether or nor turning primary rays off on an instanced object would work?

I actually moved the camera twice the distance of the reflective

reflection to get the shot out :-)
but I'd like this to work..!

Sorry it's totally unrelated...
I always got problems with prim rays and particles. In case it's of any
help, I think we ended up making a seperate pass for masking the
particles in the frame. Lame workaround but I have nothing better to suggest ;-) Arvid, there's a switch somewhere that orient the particle to the incoming ray.
Look for incoming ray under the ptype.

After some more testing I found why I couldn't see any reflections
of the particles in that particular scene, while it seemed to work in
other scenes, it's something with the view angle. But I have no idea
what the cause is, looks like a bug of some sort. I think I've nailed
the problem as shown the screenshot below. I'll upload this scene if
anyone's interested.
Here's the image: http://renderq.net/_temp/particlebug.gifAnyone else had a problem with this one?

however I'm able to turn off secondary, but that doesn't help me :-)
I'm trying to make a reflection-only pass of my particles. Any ideas?
