Backward and Forward Integration in Stream Tracer

Hi there!

Basically, I want to one-color the Streamlines where “z” component is “positive” and one-color the streamlines where the same component is “negative” (on Point / Sphere Source with center (0,0,0) )

I dont think there is a way to do that, but I think that Backward / Forward integration reffers wether the vector_r direction (considering a sphrere source) is Negative / Positive right?
