From licensee:
The project contains a small flat terrain with a basic material attached to it - just a single texture sampler connected to the base color output. Also in the project is a skeletal mesh actor, whose materials are showing fine. I'm packaging the project for Linux Arm 64 with targeted RHI set to Vulkan Mobile (ES3.1).
