Well.. appear to be random then.. hehe.
I also tried to just put some random values based on the point number into the Point node's N values. So you wouldn't need the AtribTransfer. That works fine (for me) too.
Anyway, works great. Just what I wanted.
Cheers!

Thank you, that's pretty much how far I got with my own VOP SOP. I'll show you what I mean with not entirely random. I've only replaced your cone with a cube that has the top side coloured blue.
In view 1 you get almost all cubes' blue faces, and in view 2 you get pretty much none. Is that what you mean by “alignment of the objects in Z axis still applies” ?

That is indeed what I'm having difficulty with. I can get a somewhat random rotation. But they're mostly all still pointing sort of upwards.
It's not that when you type in a 0.5 value, they rotate 180 degrees. You know? It's a vector, not rotation.
The class attribute makes sense. Where would I use it though? In the RBD initial state rotation fields? That rotates all objects at once..
Thanks for your reply.

Hi all,
Probably a newbie question etc, but I can't figure it out myself so some help would be welcome. I'm probably not grasping some of the basics..
I have scattered some points on a volume. Gives me a point cloud. I used the RBD Point Object tool to instance a box onto the points. With a Point SOP, in the particle tab you can get make random (initial) velocity and point scale.
Now how do I get those boxes to randomly rotate (different rotation per box)?
Going further, now I think about it, how would you add angular velocity, per object?
I've played around with a VOP SOP a little, to change the point normals. But that's, at least for me, not getting the boxes to be entirely random.
I've tried it with a copy SOP method too. Copy the box onto the points. Stamp random rotation ( rand($PT) ) on each box. But then I get kind of the same problem, how do you add a random per box (initial) velocity after you've imported it into DOPs (using eg. the RBD Fractured Object tool)?
I hope it's clear what I'm trying to achieve.
Based on a point cloud, I'd like objects in DOPs with random rotation, colour (I've worked out colour myself haha) and (initial) velocity.
Pretty much everything random per point / per object.
Cheers for any help.

I had the same error, although on Windows 7 x64 with a GeForce 460. It simply turned out I didn't have the latest drivers. Installing the latest drivers fixed the problem.
Hope this is of any help to you.
