Is it possible to use a custom made tree from Blender, import into Unity, add to the terrain tree paintbrush and use the Windzone effect? Ive got the terrain painting my trees but wind does not have an effect on it.
Not easily, no. Wind Zones are only designed for specific things and don't branch out from that easily at all. Here's a guide for accomplishing similar effects: https://forum.unity.com/threads/how...s-in-unity-using-tree-creator-shaders.871126/
yes however you would need a shader on the tree that handles the wind zone if you're looking for an easy way to paint the vertex color into vegetation models you can check out my asset called DE Environment that has extra tools for adding wind inti the model and a large selection of shaders with controllers DE Environment | VFX Shaders | Unity Asset Store
