Installation

Requirements

• Unity 2022.3 LTS or Unity 6
• Built-in, URP or HDRP – all shaders are Shader Graphs with Built-in, URP and HDRP targets. Built-in projects need the free Shader Graph package.

Import the package

1. Open the Package Manager (Window > Package Manager), select My Assets, find Stylized Nature - Forest Biome and click Download, then Import.
2. Keep the Arkerion Studios/Stylized Nature/Shared folder selected in the import dialog: the shaders and the sky live there.
3. Using the Built-in Render Pipeline? Install the free Shader Graph package (Window > Package Manager > Unity Registry > Shader Graph).

Render pipelines

The demo scenes are lit for URP and also open in Built-in.

• The demo Terrain has a small Arkerion Terrain Pipeline Material component that picks Unity’s default terrain material for the active pipeline. Remove it if you want to use your own terrain material.
• The demo sun has an Arkerion Sun Pipeline Intensity component. In Built-in projects with Gamma colour space (the Built-in default), or Linear colour space with Lights Use Linear Intensity off, it converts the sun brightness so the scene looks like URP instead of washing out. Everywhere else it changes nothing.
• Built-in: the demo is made for a Shadow Distance of about 150 (Project Settings > Quality, the “Ultra” default). With shorter shadow distances the far water and hills look brighter, because trees and mountains stop casting shadows there.
• HDRP uses physical light units and camera exposure. Add a Volume with an Exposure override and raise the Directional Light intensity (for example 10000 lux or more), otherwise the demo scenes look over-exposed.
• GPU Instancing is off on the materials on purpose: in Built-in, Shader Graph materials with GPU Instancing can be drawn at the wrong position. URP and HDRP batch them with the SRP Batcher, so nothing is lost there.
