- Rename lit.shader to defaultLit.shader,this one is the one written by
hand, others are generated by shader graph
- Rename littemplate to litcommon to be less confusing
- update all the scene because of renaming above
- pepare a directory with ShaderPass that are common code for a given
pass. (currently no vertex shader here)
- Add EnvTemplate to generate various combinaison of cube texarray and
simple cube for evaluteBSDF_env
- Rename class/file
- Introduce concept of FragInput
-fix issue with spotAngle that have been change in the light component
- remove undesired unrachable code warning
- create a proper shader config system (previous one was nor working)
- Change concept of material gbuffer to also include lighting, remove
all lighting buffer macro, bakeDiffuseLighting now pass to encode to
gbuffer
- deferred material is now in charge of all material RT format, lighting
buffer included
- velocity buffer is independt of deferred material
- add first start of distortion
- update velocity buffer management + add velocity pass

* HDRP: Add support of light layering for forward (first draft)
TODO:
- Test instancing
- Check perf
- add an option to disable light layer support + in frameSettings
- add deferred rendering support (mean add an optional extra GBuffer)
* Add LightLinking support (version 1 - compile)
This PR add support of LightLayers feature.
To use it, setup mask renderingLayers on renderers and LightLayers on a lights. If a logical and of both give a non 0 value, the light is apply, otherwise it isn't.
This mean that by default LightLayers is 1 and RenderingLayers is 1. Then user can say LightLayers is only 2 and it will only affect renderingLayers with 2 or 3 mask value.
LightLayers require an extra GBuffer in deferred, mean it have extra bandwidth and memory cost.
LightLayers once enabled in HDRPAsset with SupportLightLayers can be control by FrameSettings. Mean a camera can enable extra RT only for an in game cinematic.
This PR refactor...
- Shader code change: Rename GetBakedDiffuseLighting to ModifyBakedDiffuseLighting. This function now handle lighting model for transmission too. Lux meter debug mode is factor outisde.
- Shader code change: GetBakedDiffuseLighting is not call anymore in GBuffer or forward pass, including the ConvertSurfaceDataToBSDFData and GetPreLightData, this is done in ModifyBakedDiffuseLighting now
- Shader code change: Added a backBakeDiffuseLighting to BuiltinData to handle lighting for transmission
- Shader code change: Material must now call InitBuiltinData (Init all to zero + init bakeDiffuseLighting and backBakeDiffuseLighting ) and PostInitBuiltinData
- Update shader graph associate code
