Texture buffer-> 2D Texture for GPU Scene Mobile device · EpicGames/UnrealEngine@d6981a7 (github.com)
GPUSceneUseTexture2D() returns true directly for SP_OPENGL_ES3_1_ANDROID.
This differs from the doc ( Mesh Auto-Instancing on Mobile | Unreal Engine Documentation), which says for Mali we should configure it.
Seems the decision is always using Texture. However, this does not cover Vulkan.
