--------------------------
|
||||
Changes in 1.9 (not yet released)
|
||||
- BurningVideo: 0.50
|
||||
- BurningVideo: 0.51
|
||||
- 10 year anniversary update
|
||||
- Lighting model reworked. moved to eyespace like openGL. [Specular Highlights, Fog, Sphere/Reflection Map]
|
||||
- increased internal s4DVertex to support 4 Textures and 4 Colors [switchable]
|
||||
- Textures are handled as sRGB during Mipmap Generation. More accurate, less visual disruption
|
||||
- 2D is drawn as 3D like hardware drivers. [switchable]. enables viewport scaling, material2D
|
||||
- Texture Spatial Resolution Limiting working. [lower memory consumption,SOFTWARE_DRIVER_2_TEXTURE_MAXSIZE]
|
||||
- NormalMap for 1 Light accurate. still all lights are accumulated
|
||||
- SuperTuxKart 8.0.1 playable
|
||||
- Known Problems
|
||||
- Depthbuffer range not equal to Hardware Drivers. Problems with Orthographic Stencil Shadows
|
||||
- Triangle MipMap Selection. Wrong for TextureAtlas and Billboards
|
||||
- Fix CPLYMeshFileLoader checking for wrong vertex count when switching between 16/32 bit. Thanks @randomMesh for reporting.
|
||||
- Fix bug that AnimatedMeshSceneNode ignored ReadOnlyMaterials flag when checking materials for transparent render passes.
|
||||
- Unify checks if materials should use transparent render pass with new IVideoDriver::needsTransparentRenderPass function.
