A unity shader solution to generate footprint on deep 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 abedo and normal maps.
- 3.The footprints generated before will gradully be refilled and disappear.
