Hi lucek
We removed radiant angles and kept only the versions in degrees because it's easier to understand. Some brushes were created before this change and still uses the depreciated radiants, but you don't need them.
Take the "direction" bloc. it returns the direction of the stroke over 360°. Divide it by 360 (div bloc) to create a 0 to 1 value to plug in your rotation.
Then simply set your rotation from 0 to 360 in the parameters and your shape will follow your stroke.
And here is one more tip: you might see that the very first shape of your stroke always points the same way (which is normal since no direction exists before the second shape is drawn). That's why we added the "skip first shape" option in the "Flow" tab. Use it if you have this problem.
