Flow along a spline problem


Hi all,

I have just started looking at particle flow, and I’m trying to get a simple flow through a pipe, using the speed by icon and shape instance nodes.

It’s all fine, apart from when the spline is perpendicular to the PF source. If you see the attachments, the arrows have lost their position variation when the spline turns upwards.

So my question is, how can I go about this and still have the arrows in a random position?
