// PORT NOTES (Unity 2022.3 LTS / URP 14 - classic ScriptableRenderPass API)
|
||
|
|
// -------------------------------------------------------------------------------------------
|
||
|
|
// The original (Unity 6 / URP 17) implementation is built entirely on the Render Graph API
|
||
|
|
// (RecordRenderGraph / TextureHandle / RasterGraphContext). URP 14 does not have Render Graph,
|
||
|
|
// so this version uses the classic Execute(ScriptableRenderContext, ref RenderingData) API with
|
||
|
|
// manually managed RTHandles, matching the same pass structure and shader contract 1:1:
|
||
|
|
// 1) ObjectID pass -> objectID RT (+ its own depth RT if the camera uses MSAA)
|
||
|
|
// 2) Special-group pass -> customGroup RT (only if a special group is configured)
|
||
|
|
// 3) Fill ObjectID pass -> objectIDFilled RT (only if needed, same condition as original)
|
||
|
|
// 4) Blend pass -> compare RT (if comparing) or camera color
|
||
|
|
// 5) Compare pass -> camera color (if comparing)
|
||
|
|
// 6) Debug pass -> camera color (if a debug mode is active and not comparing)
|
||
|
|
// 7) Copy-back -> not needed here, see note at the bottom of Execute()
|
||
|
|
//
|
||
|
|
// Differences from the Unity 6 version worth knowing about:
|
||
|
|
// - RTHandles are allocated once and reused/reallocated on demand (RenderingUtils.ReAllocateIfNeeded)
|
||
|
|
// instead of being requested fresh from the render graph every frame.
|
||
|
|
// - `Object.FindObjectsByType` (used in the original for id-exclusion lookup) does not exist in
|
||
|
|
// 2022.3; this file uses the classic `Object.FindObjectsOfType<Volume>()` instead.
|
||
|
|
// - The classic renderer exposes `ScriptableRenderer.cameraColorTargetHandle` /
|
||
|
|
// `cameraDepthTargetHandle` directly; there is no `UniversalResourceData`/`UniversalCameraData`
|
||
|
|
// frame-data container to reroute.
|
||
|
|
// - Camera-stack detection uses the same UniversalAdditionalCameraData.cameraStack check as the
|
||
|
|
// original, kept here for parity/documentation even though the classic renderer doesn't need an
|
||
|
|
// explicit copy-back step (see the note at the end of Execute()).
|
||
|
|
//
|
||
|
|
// This file has been ported by careful, line-by-line reading of the Unity 6 implementation and the
|
||
|
|
// URP 14 classic API; it has not been compiled/run inside the Editor. Please test in your 2022.3
|
||
|
|
// project (single camera, stacked cameras, MSAA on/off, and XR if you use it) before shipping.
