The old system is still in place and is executing, alongside the new system.
Rendering will use the results of the new system, though.
Shadowmap rendering now happens after light lists have been generated.
All relevant files are in the Shadow subfolder.
The basic file structure is:
- ShadowBase.cs has interface and base class definitions
- Shadow.cs has default implementations
- Shadow.hlsl is the default header to be included by shaders
TilePass.cs currently owns the shadows via its InitShadowSystem function.
Modified ShadowManager to take an array of shadow maps instead of only one. The shadowmanager will allocate lights according to each shadowmap's supported shadows mask. Shadowmaps are traversed in order specified in the constructor. Currently there's a limit of 4 maps per light type.
Changed shadow sampling functions in shader code to support multiple comparison samplers.
Modified tilepass to pass two shadowmaps, one for directional, one for point lights, to the shadowmanager to test the new functionality. This will probably change again soon.
Merged directional and point/spot lights into the same atlas again. Added two additional atlases to support 16 bpp VSM style shadow maps.
Added new dropdown to AdditionalLightData to select precision if available.
Added a factor of 100 to the normal bias passed into the shader.
Updated shaders to use the new zw component for the normal bias offset.
Added bias offset code to point, spot and punctual routines as well.
Added support for the new shadow library to fptl.
Introduced a new shadow include inline file to support different shadow setups for different light loops per project.
Restructured the code a bit in order to support multiple instances per project.
Fixed and issue with broken shaders when one of the samplers was set to 0.
- Cleaned up some now useless code in the init code of shadow system
- Split ShadowSettings struct into two different parts. One for the init and the other for the per frame setup
- Cleaned up HDRenderPipeline a bit (mostly moving logic stuff from the asset to the instance itself)
This forces client to handle Cmd Buffer management and execution. This is necessary due to the impossibility to use nested Command Buffers currently (so any API called from user land cannot create and execute a CB of its own).
Added:
- normal+view biasing
- light view only biasing
- per sample biasing for wide PCF filters
- corner light leaking mitigation
- defines to control what type of biasing should be enabled
- a few new UI controls in the additionalshadowdata component
Removed previous biasing controls. They won't have any effect anymore.
Replaced shadow specific cubemap face function. The shadow system is now going to use the one from common.hlsl.
Renamed nrml to normal.
Added a few comments.
- Move all shader/material in Resources folder to CoreResource folder
- Move DisplayShadowMap.Shader out of Resources folder
- Pass needed material to Core function through parameters
- Update reflection system to take RenderPipeline resource into account
