So when packaging the game to Win64, in the project settings only win64 is selected as valid target platforms, yet we get 300+ warnings like this this materials failing to compile for other platforms:
UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogShaderCompilers: Warning: X:\FF-Git\Content\FF_GARAGE\Meshes\materials\lambert2.uasset: Failed to compile Material for platform GLSL_150, Default Material will be used in game.
AFAIK this is failing for Vulkan/html related targets? All materials actually work fine in the packaged build too.
