Have a look at winter environment asset pack created for quick and quality development of winter nature scenes. The set features additional shaders to adjust the amount of snow on trees, grass, and props. All trees are said to work both with the standard Unity Terrain and the Vegetation Studio system.
“AG Global Settings give you control of global wind settings such as direction, amplitude, speed, scale, and mesh stiffness. You can control the wind settings both globally across the scene and locally for each material. This allows you to adjust differently the rigidity of the objects and the influence of the wind on them.”
• Compatibility with instanced indirect by Vegetation Studio & Vegetation Studio Pro.
• Amplify Shader Editor support (v1.6.4).

• GPU global and local wind with advanced control settings (direction, amplitude, speed, size, and object stiffness).
• Real-time wind settings control directly in the scene view.
• Global and local settings for AO/Translucency/Tint Color and Snow.
• Snow on trees trunks using the wind direction
• PBR textures created from scanned data.
• All shaders support GPU instancing.
