Reflection Probes cause artifacts and texture offset when moving camera at the edge of the Probe

-

How to reproduce:
1. Open the attached “repro.zip” project
2. Open the “RefractionProblem” scene
3. In Scene View, attempt to move the camera left and right at the position shown in the reproduction video
4. Observe the result

Expected result: No artifact or texture offset on the edge of the Reflection Probe
Actual result: Texture offset and artifact appear on the edge of the Reflection Probe

Reproducible in: 2022.3.45f1, 6000.0.18f1
Could not test with: 2021.3.43f1 (Too many errors to convert project properly)

Reproducible on: Windows 11
Not reproducible on: No other environments tested

  1. Resolution Note:

    There are 2 issues reported in this case:
    1. When using multiple reflection probes with screen space refraction, you get harsh 'snapping' when the selected reflection probe changes, as there is no blending of any sort. This happens quite frequently for large meshes when moving around the camera.
    2. When using a single reflection probe with screen space refraction, there are blocky seams near the border of the reflection probes influence range, when the refractive object isn't fully contained within the reflection probes range.

    The second issue is by design, and should be worked around by making the reflection probe's range larger, or by cutting the mesh into multiple smaller pieces.

    The first issue is an unfortunate shortcoming of the current implementation. We could alleviate it by either adding blending for refractions, allowing for excluding reflection probes from refractions, or having a refraction-specific importance value. We consider this better suited as a feature request. For that reason, this bug is being closed, and we have added the potential solutions to this sub-issue to our feature backlog instead.
