- swapped fog to range based version, removed unused vertexDistance, repacked stuff it used - fixed light in tcmask to fit removed tangent invert, reorganized its vertex shader, combined and moved its lighting to world space - fixed improperly working point lights with tangent space normals - fixed uv for water - fixed shadow acnes on some objects like roofs - fixed stepped shadow cascading, now it has smooth transition - added scale-slope bias that allowed to use shadow maps with terrain Co-Authored-By: MaNGusT- <MaNGusT-@users.noreply.github.com>
- fixed light formulas to exclude multiply of shadow mapping and shadow of diffuse light to prevent over-darkening - changed scale-slope depth bias formula to a faster variant - simplified ambient light calculation for terrain shader Co-authored-by: MaNGusT- <MaNGusT-@users.noreply.github.com>
Port OpenGL shader changes to Vulkan Co-Authored-By: MaNGusT- <MaNGusT-@users.noreply.github.com>
- fixed double multiply of shadows for hq models - fixed missed shadowing on intersected geometry in hq models - fixed some features (trees) that were visible through fog of war - adjust tcmask bias Co-Authored-By: MaNGusT- <MaNGusT-@users.noreply.github.com>
For a performance win on various test systems
