Hey! The work is progressing well (although a bit slower due to holidays)! I have finished remaking white birch tree meshes set from scratch. The set now consists of 2 large, 4 medium, 4 small and 2 sapling meshes. Also the tree shader featuring wind and dynamic snow is 99% done along with a custom controller script which allows to customize the wind across all trees in the scene. Here's a screenshot and video from HDRP 7.3, curious to know what you think!
