Mobile Previewer in Standalone
Launching the game with the '-simmobile' command line argument will activate the ES2 renderer along with other mobile-related features, such as touch-based input emulation. If you only want the ES2 renderer, but no other emulation features, you can pass the '-es2' command line argument to activate the OpenGL ES2 RHI instead of the usual DirectX-based rendering. This uses nearly the exact same code path as your mobile game uses when running on device, so the graphics will appear very similar.Differences Between Previewer and Device
Differences Between Previewer and Editor
- The mobile previewer should be used when you want a more accurate representation of what your game will look like without running on your mobile device. The editor uses Direct3D and not the OpenGL ES2 renderer that mobile devices use. As a result, it cannot display some shading effects such as fog and mobile specular which require the use of OpenGL shaders.
- Debug view modes such as shader complexity, wireframe, unlit, lighting only, and lighting detail are not yet supported with the mobile previewer. If you would like to use these features you should run your game via "Play in Editor" or "Play on PC". Note however that shader complexity may not be accurate as the mobile previewer does not use the same shaders as the editor.
