Vegetation Studio Pro is a vegetation placement and rendering system designed to replace the standard tree and detail system in the Unity terrain component. It can also spawn and render vegetation on standard unity meshes.
Tested for Unity 2020.1 and 2020.2 beta.
Vegetation is spawned on the terrain based on a flexible set of rules, and controlled with both texture and polygon masks. There is also an extensive Biome system that allows you to define areas with custom biomes and splatmap rules.
Vegetation Studio Pro is based on Unity’s new Job system and Burst compiler. This allows all available cores to be used for procedural generation, culling, LOD selection and render list preparation. The Burst compiler and a data oriented structure gives a huge speed increase and a major reduction in main thread CPU use.
Vegetation Studio Pro has its own culling system and a custom render system for Vegetation.
Important - read thisIn order to use the capabilities of the job system and Burst compiler Vegetation Studio Pro has these minimum requirements:
-Scripting Runtime Version to .Net 4.x Equivalent
-Api Compatibility level to .net 4.x
In addition to this you need these 5 packages installed from the Package Manager:-Mathematics
-Post-Processing(Optional from Unity 2018.3+)
See this Setup guide for more info.
In Unity 2020.1+ make sure you have preview packages enabled to see all packages. Collectons is installed automatic by the jobs package.
For full functionality Vegetation Studio requires graphics hardware with Shader Model 5.0 and Compute shader support.
Existing Vegetation Studio users have an upgrade path to Pro. Upgrade price is the difference between the 2 assets.
Use your existing trees (SpeedTree, Nature Manufacture , Tree Creator and others), rocks and grass textures. Rendering is done using Unity’s new Instancing and Instancing Indirect system. This means no overhead on culling or handling GameObjects. Vegetation Studio should work with most vegetation shaders that support instancing. There is an online guide on how to update custom shaders to instanced indirect rendering.
You create a Vegetation Package that references your selected trees and plants. Configure the spawn rules and apply it to a terrain. The same package can be re-used on terrains in multiple scenes. Any changes done to the rule set will update the terrain directly.
