- Unity version:
- The SRP assets on the Asset Store specify the minimum version required.
- Releases on this GitHub target the built-in render pipeline, and each release specifies which version of Unity it was developed on. Currently Unity 2019.4.8 or later is the minimum version. See further down for 2018.4 support.
- Crest example content:
- The content requires a layer named Terrain which should be added to your project.
- The post processing package is used (for aesthetic reasons), if this is not present in your project you will see an unassigned script warning which you can fix by removing the offending script.
- .NET 4.x runtime
- Shader compilation target 4.5 or above
- Crest unfortunately does not support OpenGL or WebGL backends
You can download the latest version from here.
Another way to obtain Crest is to fork/clone this repository.
The files that should be copied into an existing project are under crest/Assets/Crest.
Note that crest/Assets/Crest/Crest-Examples contains example content that is useful for first time users but not required for the core Crest functionality. Furthermore, the crest/Assets/Crest/Development folder is not needed as it is only for Crest development.
The following options are no longer maintained or supported.
Crest releases are no longer published or supported.
There is a legacy branch for 2018.4 support. A direct download to an archive is available here. It is not actively developed.
If you encounter an issue, please search the Issues page to see if there is already a resolution, and if you don't find one then please report it as a new issue.
There are a few issues worth calling out here:
- Sky solutions such as Azure[Sky] requires some code to be added to the ocean shader for the fogging/scattering to work. This is a requirement of these products which typically come with instructions for what needs to be added. See the wiki for examples.
- Crest does not support OpenGL or WebGL backends
