Errors upon import

Fluffy requires Unity 2021.2 to run. If imported with and older Unity version, you will get some error messages upon import. The reason why Fluffy needs Unity2021.2 is because Unity added this new api that makes it possible to write directly to a Mesh GraphicsBuffer from a compute shader. This makes it possible to use any type of shader with Fluffy without requiring any custom shader code. It also makes fluffy compatible with all sorts of special effects like RayTracing and so on.
