This is a work I started in January.
I am experimenting with terrain built with nanite static meshes. The accuracy of the terrain has improved, but it takes more time to test and make. I will eventually improve the process based on production efficiency.
I have been improving the way the water surface is made these days. For the water disturbance, I referred to Dai Wei's solution, and the effect is satisfactory.

I still use a relatively simple method to make the water surface. I did not use Houdini to calculate the water cache.
Next is the WPO wind force of the vegetation. This is a huge workload.
