Hi Pierre,
Thanks for the question. You can do this by using the
Random Number node to choose when to randomise the segments. This node has several choose for when a Random number is generated, including per segment, per X Spline, per RailClone object, per Array Y Row, and per X spline section. In this case I would use it by wiring it to the
Z Fixed rotation input of a
Transform operator.
I see in your style you have used 3 different version shutter angles using Fixed rotations. In this case you could connect the 3
Compose nodes to a
Selector operator, Export the
Index, and wire it to the
Random node. In both cases, you should set the Random node's Generate On property to
X Spline Start.
I've attached a sample file for the first technique which should give you more variations. I hope that helps, please let me know if you have any further questions.
Many thanks!
Paul.
