• Removed RenderFullscreenQuad from ScriptableRenderer. Use CommandBuffer.DrawMesh and RenderingUtils.fullscreenMesh instead.
• Removed RenderPostProcess from ScriptableRenderer. Use ScriptableRenderPass.RenderPostProcessing instead.

[2.0.0-preview]

Added

• Explicit render target load/store actions were added to improve tile utilization
• Camera opaque color can be requested on the pipeline asset. It can be accessed in the shader by defining a _CameraOpaqueTexture. This can be used as an alternative to GrabPass.
• Dynamic Batching can be enabled in the pipeline asset
• Pipeline now strips unused or invalid variants and passes based on selected pipeline capabilities in the asset. This reduces build and memory consuption on target.
• Shader stripping settings were added to pipeline asset

Changed

Pipeline

• Pipeline code is now more modular and extensible. A ForwardRenderer class is initialized by the pipeline with RenderingData and it's responsible for enqueueing and executing passes. In the future pluggable renderers will be supported.
• On mobile 1 directional light + up to 4 local lights (point or spot) are computed
• On other platforms 1 directional light + up to 8 local lights are computed
• Multiple shadow casting lights are supported. Currently only 1 directional + 4 spots light shadows.

Shading Framework

• Directional Lights are always considered a main light in shader. They have a fast shading path with no branching and no indexing.
• GetMainLight() is provided in shader to initialize Light struct with main light shading data.
• Directional lights have a dedicated shadowmap for performance reasons. Shadow coord always comes from interpolator.
• MainLigthRealtimeShadowAttenuation(float4 shadowCoord) is provided to compute main light realtime shadows.
• Spot and Point lights are always shaded in the light loop. Branching on uniform and indexing happens when shading them.
• GetLight(half index, float3 positionWS) is provided in shader to initialize Light struct for spot and point lights.
• Spot light shadows are baked into a single shadow atlas.
• Shadow coord for spot lights is always computed on fragment.
• Use LocalLightShadowAttenuation(int lightIndex, float3 positionWS) to comppute realtime shadows for spot lights.
