DrawingSettings describes how to sort visible objects (sortingSettings) and which shader passes to use (shaderPassName).

OverrideMaterial vs. OverrideShader: Using the overrideMaterial parameter will override all rendered materials and their properties. The overrideShader property will force the renderers to use a different shader while preserving current material properties. Properties on the overriden material can then be accessed in the override shader. The use of override shaders is currently not supported with SRPBatcher and BatchRendererGroups. Override Shaders will have an impact on performance and should be avoided where overrideMaterial can be used. OverrideShader and OverrideMaterial can't both be used in the same drawRenderers call.
