Crashes when using camera.SetTargetBuffers on IOS11 if external display is attached
Unity crashes on IOS11 if external display is attached
XCode Version 9.0 beta 6 (9M214v) Unity 2017.1.1p1 IOS 11 beta.
1) Build your app to your device 2) Attach external display 3) Start the app.
I copied the code exactly from the example in the documentation: https://docs.unity3d.com/ScriptReference/Display.html
public class TTDisplay : MonoBehaviour
{
public Camera itsExternalCamera;
public Camera itsMainCamera;
void Start()
{
// GUI is rendered with last camera.
// As we want it to end up in the main screen, make sure main camera is the last one drawn.
itsExternalCamera.depth = itsMainCamera.depth - 1;
itsMainCamera.SetTargetBuffers(Display.main.colorBuffer, Display.main.depthBuffer);
itsExternalCamera.enabled = false;
}
void Update()
{
if (Display.displays.Length > 1 && !itsExternalCamera.enabled)
{
Display.displays[1].SetRenderingResolution(256, 256);
itsExternalCamera.SetTargetBuffers(Display.displays[1].colorBuffer, Display.displays[1].depthBuffer);
}
itsExternalCamera.enabled = Display.displays.Length > 1;
}
}
I submitted a bugreport today. Anyone else has this issue? Best wishes,
Michal
We can reproduce this crash only on IPad Air1 at the moment. IPad Pro is working fine.
Found a similar crash using XCode 9.1 beta build iOS 11. Every time I enter a scene with a custom shadow rendered by a render texture, it crashed.
The log says ' ... texture at depth attachment has usage ... '
After a little search, one said, metal need a rendertexture to marked with MTLTextureDescriptor, otherwise an exception will be thrown.
Then I build the game with GLES 3.0 instead of metal, and it never crashed.
So I think I've nailed the issue. the question is when will Unity upgrade to solve that?
