I want to make wind animation for vegetation using Vertex Colours for game engines.
I've seen some great documentation on how to do it in UE4 with Max (pivot painter).
But I want to do this with Blender, and also export to Unity.
For Unity there's an asset called "Pivot Brush" with which you can vertex paint on meshes in-editor.
But I don't want to rely on beta third party assets.
So how can I paint vertex colours and export that information to UE4/Unity?
Do I have to bake those vertex colours on as a texture?
Do I have to Link/Rig leaves/Twigs/Branches?
I have never done this, and surprisingly can't find much information on how to do this besides UE4 with Max.
Can someone atleast point me into the right direction, as I am new to this?
