Right Click all of your splines and check Vertex Ticks in the Display Properties. Now you can see every vertex on the spline. The spacing between every vertex is set by the Segment Length of the Normalize Spline modifier, that´s why we need it!

Now convert your spline into an edit poly by right clicking it and using the Convert To operation.

NOW if you didn’t set the interpolation steps to 0 you will have a looooot of vertices and we don’t want that! The interpolation steps insert the amount of steps into each space…

Step 4: Let´s get back to the flow… ;) At first we need to add a birth script node to replace the birth node already existing. Write this script:

Replace the “§guide” with the name of your guides leaving the leading §-sign.

Short explanation:
The script cycles through the vertecies of the mesh (§guide) and plants a particle at every vertex.

Step 5: Replace the Shape node with a Shape Instance and pick the object you want to plant onto the guides we just created. In my case stadium chairs.

I added a Scale node as well to have full control about the scaling within particle flow. Maybe you want a more random scaling then you should increase the scale variation e.g.

TIP: Set the Display operator to “BoundingBox” so that you can see the actual direction without the need of calculating the entire geometry instances!
