Hey! 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!

Dude I love you. These kind of tutorial never go in depth and never speak about performance issues, which is the main problem when actually trying to ship something. Thanks a lot!
-
This is absolute platinum of a learning resource, just loads of well organized good to know, shown clearly and concisely. This is going to be providing immense benefit to so many artists for years to come
-
The top-down orthographic render method to get the ground texture kind of blew my mind. I've been making landscapes for years and such an obviously simple solution never crossed my mind. Thanks!
-
Ghislain Girardot tutorials are gold. 10/10 IGN
-
1 hour grass tutorial wtf....AND I'M ALL UP FOR IT, brb snacks :D
-
Man, you're insane. Thank u so much for providing something clearly like this.
-
I just recently started using UE5 and I was struggling to make a proper landscape and get the grass to work, thank you so much for giving such an extensive tutorial!! I've looked through many videos and this one is by far the most thorough one :) thank you!
-
Absolute banger of a video!
-
me being completely lost the whole video Ghislain: buckle up, heres where things get tricky
-
Loving your new video format man. Thanks for all of this knowledge
-
Wow I really need to try this out for my next project!
-
This is now my favorite Video on YouTube and I am so thankful for it! This is such a nice learning ressource and I can not wait to recreate it step by step. It might take me a full week to really grasp all the vector magic necessary, but with your clear explanation I will manage. I do truly love you for your work and we are blessed to be gifted with all of it, especially with it all being so accessible and free. Thank you so much! 🙏
-
Been anxiously waiting for this video. What a perfectly thorough tutorial! Thanks for making a cool grass shader seem a lot less daunting.
-
This will be the video I'll return too when I need to do grass again. Not being much of an artist, this is the sort of thing I struggle with. Nice to see all the different approaches. Nice work.
-
Thank you very much for your wonderful sharing. By the way, I find that ClumpMap or ScaleMap can be used to add more color variations, such as grass that grows very lush due to organic matter accumulation, and their color will be more saturated. I applied them to my grass and they looked better👍.

tres tres bon video, merci boku

Amazing video, I love that you explain the reasoning behind every choice, elaborate on the various options and suggest various ideas to experiment with. This was really informative also the grass tiling texture trick seems so simple but it's small things like that, that people can miss so easily or try to come up with something more complicated when a good solution to a problem is right in front of you.

What a masterclass, and the work that went into making the video and visually explaining concepts and techniques is equally amazing. Subscribed to Patreon.
