Nikolaus Schatz shows how you can visualize airflow in C4D using splines.

Splines are extraordinarily useful components in 3D. You can use a spline as construction for modeling, reference or rendering, or all three. This new tutorial from Nikolaus Schatz shows how you can use splines to create a simple airflow visualization, like the one seen on the Xbox explainer.

The tutorial shows why hair rendering may not be the way to go, and then finalizes the experiment by using Octane to create the shaders and render the animation.
