Description

A SceneCaptureComponent2D is able to correctly capture the infinite hallway effect for portals. The " X 100% Y 100%" of ScreenAlignedUVs node is necessary to create the material that produces the correct scene in relative to player camera's location and rotation. The " X 100% Y 100%" of ScreenAlignedUVs node doesn't allow the portal material to be correctly rendered when it is captured by its own scene capture.

Found in 4.20 CL# 4369336, 4.21 CL# 4541578, 4.22 CL# 4589258 

Steps to Reproduce
  1. Open linked project [Link Removed]
  2. Play in Editor
  3. Look at both of the Scenecapture2D blueprints labeled "Endless Reflection(portal)"

Results:
One will have an infinite hallway effect for the reflection and the other will not. This is due to the material using ScreenAlignedUVs.

Expected:

Both would have the same effect regardless of the ScreenAlignedUVs node.
