Just as a clarification to that last setup.
You're using count mode set to a random value - from the help it mentions that count would just stretch the count number of segments along the spline unless an x-evenly input is set to divide the spline.
Am I to think that the x-evenly, if it had a model input, would calculate the width of the model in the evenly input and then fit the default input model in the gaps between them? So in our case, if our evenly input was 100cm wide and the distance was set to 600cm, this would shrink the gaps for the default to fit into to 500cm? Hence if you're using an evenly input that has no width, it'll just use the full 600cm for an individual copy of the default model?
Would this almost point to a missing mode for default - count is setting the width by the amount of times it can fit along the spline length, would it make sense to have a count by width mode too rather than needing to short circuit it with the sneaky zero width evenly trick?
Thanks again for this!
