HDRP Basics Demos series, part 4 of 6 rendered and captured in real-time

started porting my systems to HDRP in late 2019, using all custom shader (no use of shader graph, vfx graph, etc)

this series showcases basic rendering sanity checks for the custom shader hacks as well as testing HDRP volumetric fog, lighting feature, improved shadows and depth of field

all natural process: no use of noise, patterns or external lookups in the sim itself
