I'm trying to generate lots of rails using "animation nodes" and after "googling" I have something like this on the screen. But I have one problem, I don't know how to use more than one object for this crosswise planks.

Right now I have connected "Object Instancer" , how can I add multiple object instancer with random placing of this planks?

In other words I'm looking for a methods to duplicate randomly 3 elements along the curve.

Best!

  • $\begingroup$ Please use the animation-nodes tag for questions related to Animation Nodes. Can you tell me exactly what you expect the output to be? Maybe place some of them by hand so that I can see the result you are after. $\endgroup$ – Omar Emara Mar 7 '18 at 19:48
  • $\begingroup$ I can't use my computer right now but it's feiry simple to describe. I'm looking for method to duplicate or instance 3 objects along the curve in random order. Right now I have only one plank connected to rails but it's will be cool to use more different shapes of them for more variety look of train rails. Ps. Animation-node tag submitted ;) $\endgroup$ – Despoa Mar 8 '18 at 8:02

Instead of instancing a single object, create a number of empty objects using the Object Instancer Node with the Copy From Source option disabled. Then get a list of all objects that has the meshes you want, generate a random list from them using the Random List Node and copy the data from the objects in this list to the empty objects you created using the Copy Object Data Node.
