On Wednesday I finished up the grass wind effect:
I combined the effect from the tutorial with the animated sine effect seen in the G channel of the simple grass wind, which ended up being more complicated than it probably needed to be. In the future I would also avoid using the SimpleGrassWind node and instead simply create the sine wave myself, as it would probably be cheaper than only using a slice of an entire function node.
I also created a Global Material Parameter for the scene so that I could edit several different materials through the blueprints:
After I'd finished this base effect, I created a wind blueprint to add some more variation in movement to the scene:

| Play Sound at Location nodes were added later |
This was set to slowly change between two different wind directions:
After this had been completed, I set to work on adding a reaction to the player moving around in the grass following
this tutorial:
I have thought about the cost of using event tick for the grass, and have tried using a delay to offset the cost, however each time it resulted in the grass looking janky as the frame rate simply wasn't smooth enough. I may go back to it later and try with even smaller numbers however, as any kind of delay would be less costly than using an event tick on its own.
