Re: Turn off primary rays for particles...

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:

Anyone else had a problem with this one?

...doesn't seem to work. The particles dissapear all together, 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?
