URP管线自身代码问题

7.7.1

• 修复通过 CameraCaptureBridge.AddCaptureAction 抓屏抓到的是没经过后处理的

  • 408行开始

                if (renderingData.cameraData.captureActions != null)
                {
                    m_CapturePass.Setup(m_ActiveCameraColorAttachment);
                    EnqueuePass(m_CapturePass);
                }
    
                // if we applied post-processing for this camera it means current active texture is m_AfterPostProcessColor
                var sourceForFinalPass = (applyPostProcessing) ? m_AfterPostProcessColor : m_ActiveCameraColorAttachment;
    

    替换为

                // if we applied post-processing for this camera it means current active texture is m_AfterPostProcessColor
                var sourceForFinalPass = (applyPostProcessing) ? m_AfterPostProcessColor : m_ActiveCameraColorAttachment;

                    m_CapturePass.Setup(sourceForFinalPass);
                    EnqueuePass(m_CapturePass);

        applyFinalPostProcessing ||
        // no final PP but we have PP stack. In that case it blit unless there are render pass after PP

        // offscreen camera rendering to a texture, we don't need a blit pass to resolve to screen
        m_ActiveCameraColorAttachment == RenderTargetHandle.CameraTarget;
    

    替换为

        bool cameraTargetResolved =
        // final PP always blit to camera target
        applyFinalPostProcessing ||
        // no final PP but we have PP stack. In that case it blit unless there are render pass after PP

        // offscreen camera rendering to a texture, we don't need a blit pass to resolve to screen
        m_ActiveCameraColorAttachment == RenderTargetHandle.CameraTarget;
    

• 修复启用 UniversalRenderPipelineAsset 的 MSAA 后，通过 ScreenCapture.CaptureScreenshotIntoRenderTexture 抓屏出错
  7.3.1没有这个问题
  这个也不是URP代码问题，问题出在传入的 texture 上，该 texture 创建时不要设置
  m_texture.antiAliasing = QualitySettings.antiAliasing;
