When using an RVT with BaseColor/Normal/Roughness format on DX12 with a GPU that supports Tier2, a GPU crash may be seen.
Open the TM-RuntimeVirtualTextures map in QAGame.
Open the asset /Game/Maps/Tools/VirtualTexture/RVT_Landscape.uasset
Change "Virtual texture content" to "Base Color, Normal, Roughness"
Observe GPU hang.
After the fix, there should be no hang, but the RVT change will make the map appear grey/incorrect until the associated materials are fixed up. To do that select the RVT asset in the content browser, and in its context menu select "Fix material usage". Even after this the map won't look exactly as it did before the RVT change, because specular is not handled by the format. This isn't a bug.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-186950 in the post.
