# Changelog

## [2018.2 undecided]

### Improvements
- Add stripper of shader variant when building a player. Save shader compile time.
- Disable per-object culling that was executed in C++ in HD whereas it was not used (Optimization)
- Enable texture streaming debugging (was not working before 2018.2)

### Changed, Removals and deprecations
- Removed GlobalLightLoopSettings.maxPlanarReflectionProbes and instead use value of GlobalLightLoopSettings.planarReflectionProbeCacheSize

## [2018.1 undecided]

### Improvements
- Configure the volumetric lighting code path to be on by default
- Trigger a build exception when trying to build an unsupported platform
- Introduce the VolumetricLightingController component, which can (and should) be placed on the camera, and allows one to control the near and the far plane of the V-Buffer (volumetric "froxel" buffer) along with the depth distribution (from logarithmic to linear)

### Changed, Removals and deprecations
- Remove Resource folder of PreIntegratedFGD and add the resource to RenderPipeline Asset
- Default number of planar reflection change from 4 to 2

### Bug fixes
- Fix ConvertPhysicalLightIntensityToLightIntensity() function used when creating light from script to match HDLightEditor behavior
- Fix numerical issues with the default value of mean free path of volumetric fog 
- Fix the bug preventing decals from coexisting with density volumes 

## [2018.1.0f2]

### Improvements
- Screen Space Refraction projection model (Proxy raycasting, HiZ raymarching)
- Screen Space Refraction settings as volume component
- Added buffered frame history per camera
- Port Global Density Volumes to the Interpolation Volume System.
- Optimize ImportanceSampleLambert() to not require the tangent frame.
- Generalize SampleVBuffer() to handle different sampling and reconstruction methods.
- Improve the quality of volumetric lighting reprojection.
- Optimize Morton Order code in the Subsurface Scattering pass.
- Planar Reflection Probe support roughness (gaussian convolution of captured probe)
- Use an atlas instead of a texture array for cluster transparent decals
- Add a debug view to visualize the decal atlas
- Only store decal textures to atlas if decal is visible, debounce out of memory decal atlas warning.
- Add manipulator gizmo on decal to improve authoring workflow
- Add a minimal StackLit material (work in progress, this version can be used as template to add new material)

### Changed, Removals and deprecations
- EnableShadowMask in FrameSettings (But shadowMaskSupport still disable by default)
- Forced Planar Probe update modes to (Realtime, Every Update, Mirror Camera)
- Removed Planar Probe mirror plane position and normal fields in inspector, always display mirror plane and normal gizmos
- Screen Space Refraction proxy model uses the proxy of the first environment light (Reflection probe/Planar probe) or the sky
- Moved RTHandle static methods to RTHandles
- Renamed RTHandle to RTHandleSystem.RTHandle
- Move code for PreIntegratedFDG (Lit.shader) into its dedicated folder to be share with other material
- Move code for LTCArea (Lit.shader) into its dedicated folder to be share with other material
 
### Bug fixes
- Fix fog flags in scene view is now taken into account
- Fix sky in preview windows that were disappearing after a load of a new level
- Fix numerical issues in IntersectRayAABB().
- Fix alpha blending of volumetric lighting with transparent objects.
- Fix the near plane of the V-Buffer causing out-of-bounds look-ups in the clustered data structure.
- Depth and color pyramid are properly computed and sampled when the camera renders inside a viewport of a RTHandle.
- Fix decal atlas debug view to work correctly when shadow atlas view is also enabled
