For example, a detailed 3km mesh set to static will require settings adjusted much lower than default. Lightmaps can include both direct and indirect light. The Decode Lightmap node decodes color from Unity lightmap (RGBM or dLDR depending on platform). If you will bake Lightmaps for your mesh, Enable Generate Lightmap UVs only if your mesh doesn't have a good UVs for lightmap baking, for example overlapping UVs are BAD!
