Thanks for the reply, Jerome.
My understanding was that each particle should have its own rotation (-value), so it doesn’t look too artificial (?) perhaps. (”...if it’s possible to apply random HPB values to each particle individually…”
I could read in it that each particle becomes randomly new rotational values, perhaps for each frame, and/or for each single one. Am I too far off with my interpretations…?
The PRolling, accordingly to the Help-Content: With this node, you can achieve two different types of effect. You can use it to roll particles over a surface — the larger the particle, the longer each revolution takes. The second effect is to distort the size of the particles based on their speed. This enables you to create the squash and stretch effect of objects such as tennis balls, or effects that are similar to motion blur.
Which is more complex than the:
PSpin: This node controls the rotation speed and direction (i.e. the spin) of particles about their axis systems.
Both are useful with no question.
Enjoy your exploration :o)
