Ran into a Fixed bug UE-53126

UE 4.18.2 (Launcher Installation) Android ES2 build, Clean Project With Landscape, encountered link:UE-53126

Spamming incomprehensible warnings during packaging.


LogLandscape: Warning: Shader XYZ unknown by landscape thumbnail material, please add to either AllowedShaderTypes or ExcludedShaderTypes

Im aware of the ES2 shader limitations etc.
I asure its not of my doing as far as im aware.

Also: %localappdata%\UnrealEngine\Common\DerivedDataCache deletion didnot resolve the issue.

Should I update engine from 4.18.2.to 4.18.3 ?

…Or is it not going to matter because it was fixed on Dec 7, 2017
