Item description:

Complementary Shaders are specialised to be issueless as possible. This means that everything you will see in this pack was meant to be used in gameplay. This shaderpack (at first, BSL) was used in survival with many people for months, and it has been developed/edited according to what people wanted. The end result is a pack that comes with a resource pack that has to be used in order to make everything look as they should. This resource pack is used to give the shaderpack more information about how it should render blocks. But if you aren't going to play vanilla, then you can enable the "Compatibility Mode" and make the shader compatible with nearly everything.
