Virtual Texture - 4.25 Crash

Development Rendering
1

When I play in editor or standalone and change the graphics from low or medium to high or epic the editor will crash. It didn’t do this prior to creating a skeletal mesh with UDIMs and thus uses virtual texturing.

I’ve tried to verify my installation of Unreal Engine 4. Removing the textures from my project fixes the crash, but that is not ideal.

Still happens in 4.27 and not a lot of information to go by on it.
