I ran an Android 3D app made with Godot 3.5.2 and GLES2 renderer on an Android emulator called BlueStacks X, but I could only see a black screen when playing a 3D scene, despite having set the graphics renderer of the Android emulator (BlueStacks X) to Vulkan:
If I play a 2D scene that only consists of CanvasLayer, Controls, TouchScreenButtons and Sprites without any 3D object, I can see the user interface.
Have you ever tested a 3D mobile game made with Godot on an Android emulator? What is the best Android emulator for testing purposes?
