Contrail brush that I’ve created. It’s not complete - I want to add some texture and blending in the end of the stroke, as well as make some size adjustments. Though it is usable now, you can draw simple strokes in the sky to make contrails. please enjoy.

Here’s how it may work close-up. The brush is sensitive to speed and adjusts to your chosen Color, so it’s not necessary to be white. I will edit the material later and after fully finishing I plan to charge for it a little.
