HYPER-REALISTIC Grass Wind Animation [UE4, valid for UE5]

[DISCLAIMER] I know, this video is not very easy to follow, it requires some more than basic knowledge of the subject, but I think everyone should be able to wrap up his head around it eventually. Here I illustrate my personal take on getting a realistic and good looking wind animation for the grass. As always I’m more than open to any feedback and discussion, so feel free to express your thoughts in the comment section :) This scene can be downloaded here: Discord: Patreon: 00:00 - Intro 00:10 - Listing out the rules to my approach 01:22 - Explaining the basic idea 04:55 - Working out the math for the bending deformation 15:40 - Giving a thickness to the segment 21:25 - Moving to Unreal (?) ... adding the 3rd dimension 25:00 - Wrapping up the final formulas and copying them to UE 27:46 - Improving the visual quality 36:45 - Animating the wind 44:55 - Adding randomness 48:45 - Final thoughts and a challenge for you
