When a POM decal material is applied to a decal actor in the scene the video driver will crash. This worked prior to 4.11.0 release. Only when the material is assigned to a decal actor will the video driver crash. If the Material is changed to "surface" and applied to the floor static mesh it works as intended.

POM material setup image attached if the project isn't needed.

This is a regression of behavior that worked in 4.10.4, but no longer works in 4.11 or later builds.

Tested in the following builds:

-4.10.4 CL-2872498 - Works
-4.11.2 CL-2954100 - Broken
-4.13.0 CL-2955029 - Broken


Steps to Reproduce

1. Download and Open attached Test Project
2. Open PomTest.umap

Regression: Yes

Results: The POM material assigned to Deferred Decal Actor will cause the video driver to crash.

Expected: The Video driver will not crash.
