Source Code: Godot 2D Multimeshinstance2D Swaying Grass

Downloadable source code. This would not be possible without all the help I've gotten from various sources over the years!

Features:

"Y-Sorting" for any amount of objects. Individual swaying for each grass tuft. Decent performance (1100 FPS on RX 5700).

How to:

It uses rows of MultimeshInstance2D. This is so we can use position.y = z_index as a Y-Sort replacement for the grass and actors. Then we use some shader code on the textures to make them sway. Limiting factor of performance is number of rows.

Todo:

Since z_index has some limitations on max value it might be best to set z_index in relation to the camera for each object if using larger levels.
And it might be best to relocate the rows of grass to follow the camera.
