I need to support Metal API in my APP.
and I tested MetalGL sample demo.
but It doesn’t simultaneously run opengl-es 2.0 and Metal API in an APP.
the mean. i want to contain in an app.(ex. iphone4s run on open-gl es2.0. iphone5 or high device run on Metal)
Vainglory game can run both iphone4s(opengl-es) and iphone5 or high device (metal api).
how to solve on MetalGL?2016-01-12 at 11:58 am #775
MetalGL will automatically run native OpenGL ES when running on a 32-bit arm7 device like the iPhone 4S.
You don’t need to do anything to enable this, but make sure that you are not forcing the value of the

I response below e-mail about two week ago.
i didn’t touch your sample. just compiled and ran on my ipad2.
how can i run?
In future, please submit support questions to the MetalGL forum.
The samples supplied with MetalGL are designed to allow you to easily compare running the same app under Metal or OpenGL ES.
To do this, the samples include the compiler build setting MGL_SUPPORT_OPENGL_ON_METAL, which you can turn on or off to select either Metal or OpenGL ES. You can learn more about this in the Comparing MetalGL against OpenGL ES section of the README-SampleProjects.md file.
In the MetalGL sample apps, the default setting for this build setting is to enable Metal, which on a device that does not support Metal causes the issue that you have encountered. To allow a MetalGL sample app to run on a device that does not support Metal, you can either set the value of this build setting to 0 (MGL_SUPPORT_OPENGL_ON_METAL = 0), or remove the build setting from the app, and allow MetalGL to automatically determine whether or not to use Metal.
In your own app, you would not include this build setting, and allow MetaGL to automatically determine whether or not to use Metal, based on the capabilities of each device.

Subject: unsupported device test with iPad2.
hi I’m a korea developer Oneal Jang.
I just tested unsupported device with iPad2.
if your app does not support Metal , use of the native OpenGL ES 2.0?
[mgl-info] OpenGL functionality using Metal cannot be provided because Metal is not supported on this device. OpenGL functionality provided by native OpenGL framework.
