2.Compatibilty #

Unity version
The minimum supported version is Unity 6000.0.23 LTS

Render Graph Compatibility Mode must be disabled.

Scriptable Render Pipeline
Only compatible with the Universal Render Pipeline, minimum required version is 10.3.2. HDRP support will unfortunately not be added, as this practically requires everything to be rebuild from the ground up + indefinite support/maintenance.

Unity version Status
Unity 2022.3 Incompatible
Unity <6.000.0.23 Unsupported
Unity 6.000.23+ Supported
Unity 6.1 Obsolete
Unity 6.2 Obsolete
Unity 6.3 Supported
  • There is little reason to not use an LTS version, hence tech versions (eg 6.1-6.2) are no longer involved in testing.

Please note that every URP version release tends to break something. Changes to the URP shader libraries are undocumented, so it takes some time before the package is compatible with newer versions. Unless a maximum version is stated here or on the store page, it is compatible with all higher versions of the URP.

All rendering paths are supported

VR
The shader does not use anything that requires VR-specific code, hence there’s no compatibility concerns. Has been tested using an Oculus Rift where no issues have been encountered.

Note that the shader has an “Alpha to coverage” feature which will greatly reduce aliasing when MSAA is used.

Mobile
Mobile platforms are very sensitive to alpha-tested shaders and overdraw (surfaces rendering over each other) which is very common when it comes to grass. This is one of the main reasons why the shader cannot be optimized for mobile as previous tests have indicated.

As such, mobile hardware is not considered as supported, nor advertised as a compatible platform.

WebGL/WebGPU

This uses the OpenGLES 3.0 graphics API, which is supported.

MacOS
Compatible with both the OpenGL and Metal graphics API’s.

Consoles
Tested via a third party on Playstation 4, where no issues were present. Verified to work on Xbox One X (UWP). The shader is similar to the Lit/Simple Lit shader in the URP. This leads to assume the chance of any graphical or compiling issues are minimal.

Shader runs without any issues on Nintendo Switch, but performance is a pressing issue. In general, the platform is very sensitive to alpha tested/cutout materials, which is the biggest performance hit. This is pretty much a requirement for a grass shader, so this limits the amount of grass that can be visible at a time.

Third party integrations

Unlike, the Unity 2021-2022 version, this version no longer supports the Curved World asset. This is attributed to the fact that the grass shader no longer has the “.shader” file extension. Support for other file extensions, for Curved World’s shader activator was requested in 2024, but was hasn’t been added at this time.
