- Remove DiffuseRoughness shader param, add SpecularExponent shader param
|
||||
- Change R_SubdividePatchToGrid() to subdivide patches more evenly
|
||||
- Calculate tangent space in fragment shader instead of storing per vertex
|
||||
- Fix sun flare with sky portals. Sun flare must be inside sky portal.
