A unity shader solution to generate footprint on thick snow surfaces.
Need shader model 4 or up to support the hull/domain/geometry shaders.
Currently written for deferred shading path.
Unity Version: 5.5.1f1.
- 1.Dynamic subdivide and displace the snow ground surface.
- 2.Generate local UV coordinates to load detailed footprint’s albedo and normal maps.
- 3.The footprints generated before will gradully be refilled and disappear.
