Glad to hear it’s working for you!
The video you sent is actually a simplified version of the method I was referring to earlier! Check out this series on the same subject by PrismaticaDev:
In his tutorial, he uses the same method but generates a vector map. This can lead to a lot of new and interesting effects- such as displacing grass away from the player instead of just downwards, and if plugged into a particle system, can provide a movement direction. I’ve even seen more compilated versions of this effect where a noise animation is factored in to the texture to create some great procedural movement.
All that to say, getting the base effect is very simple, but if you’re looking to learn more / expand your system, the sky is the limit!
