Metal on iOS doesn't work *at all*

yolque commented 8 years ago

OK, I know the release notes say "Metal is not fully supported on iOS", but still...

Steps to reproduce:

Create a new empty project, import the GVR package and load the Cardboard headset demo
Publish for iOS with Auto Graphics API
Build on Xcode, start -> crash at startup

This happens on both GVR 0.9.1 and 1.0. With OpenGLES2 it works fine.

Phone: iPhone 6s Plus iOS: 10.0.2 Unity: 5.4.1p2 Xcode:8.0

Xcode debugger says it crashes here:

0x100888b2c <+1500>: b 0x100888b48 ; <+1528> [inlined] GetPrimitiveCount at GfxDeviceMetal.mm:626

Console log from 1.9.1:

Add a delegate to SceneManager.sceneLoaded instead to get notifications after scene loading has completed

Yes. This is a known issue as mentioned. It'll be fixed in our next release, but if it's critical to you I suggest you drop back to 0.9.1.

I downgrade to 0.9.1 and I am using Xcode 8 and I am still getting the same error. Does anybody have another solution?

jaraen commented 7 years ago

same here :( I have error "failed assertion `missing sampler binding at index 0 for _mtlsmp__MainTex[0]" running 0.9.1 and xcode 8

Bersaelor commented 7 years ago

Unfortunately I encoured the error just now. GearVR version v1.0.1 and xcode8.

Just mentioning since @nathanmartz said it'll be fixed in the next release.

Has this been fixed? Please let me know! I just tried it with xcode 8 and im facing this issue

gratco commented 7 years ago

I had the issue when I had a UI scene with jpgs in it. If I only run the 3D scene it works.

AliasSCM commented 7 years ago

I have a 3d scene with an imported fbx model. Its a single fbx model with materials applied to it. Im not sure whats happening at this point. It works on the play mode in the editor but crashes when i try to launch it as an iOS app.

Is this a problem with the fbx? Or something to do with the latest version of xcode. I use xcode 8 and unity 5.4.
