Here's my long awaited stylized grass breakdown/tutorial/course/whatever-it-ended-up-being. Apologies for the very long video, I tried to make it as beginner friendly as possible while trying my best to explain quite a few complicated techniques, so the duration exploded! I might have over-explained some things here & there so feel free to use the timestamp to skip to the good parts! Huge thanks to my patreon supporters for making this video possible. Feel free to join in if you want to see more videos like this one! I hope you'll like the video, cheers!
