Motion Vector texture reports incorrect Mesh data when Mesh is coming from off-screen
Reproduction steps:
1. Open the attached “MBlurIssue.zip” Project
2. Open the “Scenes/SampleScene” scene
3. Enter the Play mode
4. Observe the Motion Vectors in the Game View
Expected result: The “Motion Vectors” data points in the correct direction for mesh data that was off-screen the previous frame, showing green on the right and yellow on the left
Actual result: The “Motion Vectors" data points in the negative direction for mesh data that was off-screen the previous frame, showing the black and red band at the bottom
Reproducible with: 2021.3.37f1, 2022.3.22f1, 2023.2.17f1, 6000.0.0b13
Reproducible on: Windows 11
Not reproducible with: No other environment tested
Note:
- The reported is using a custom Renderer Feature “MotionBlurRendererFeature” that shows Motion Vectors

Resolution Note:
Hi there
I took a look at this, and don't think the issue is with URP. Doing a RenderDoc capture shows that the motion vector texture is generated as expected, without the artifacts from the custom debug view. It's possible that you might not be interpreting the texture correctly.
