# Shader Warnings

## Basic Information

When importing a package, you may see a large number of shader warnings and compile errors. This is because packages ship with shaders for a wide variety of Unity and SRP versions. Some of these are not compatible with each other, or even different versions of Unity. 

Don't worry -- we've shipped versions compatible with HDRP 7 (2019 LTS), HDRP 4 (2018 LTS), Universal (2019) and the Standard Renderer (2018+). 

The system will automatically pick the right shaders when you build your character assets.
