What this tool does
It let's you paint billboard trees all across the scene. Trees can be painted onto anything that has a collider.

When it is useful
- you want to have forests on a non-unity terrain
- you want to have large, dense forests in the distance

Features
- Paint trees with 3 different methods: Spraypaint, Fixed Density and Precise Place
- Paint over multiple objects
- Nicely spaced trees
- Tree editor
- Randomize width and height
- Painting can be undone / redone
- Billboard trees rotated via shader
- High preformance forests
- Supports point and spotlights. Only on the Built-in Render Pipeline
- Example included
- Guide included (Html)

Supported render pipelines
The forests can either be using surface or vertex-fragment shaders.
While vert-frag shaders are supported on the built-in RP, LWRP and URP, surface shaders are only supported on the built-in render pipeline.
The vert-frag shader only supports one directional light.

Preformance
The trees are billboard trees and they are being rotated - towards the camera - via a shader. This allows the forests produced by this tool to be really fast and low cost, even if they are large and dense.
