Spent a few days with this shot! Animated the grass and lalang fur by hair simulation, and then animating the movement of the stem manually by keyframe. The lalang is rigged using an IK handle.
I also have the sun rising! But all these shall be confidential for now, in order not to spoil you 🙂
The next step would be to render these out and add some low mountains in the distance by matte painting. That should make it ready for compositing.
