Unity 5
SDK Mobile for deep
changes
Starting on unity

10. Prototype! Prototype!
Prototype!

11. Go Horse!
Look for FUN
FAIL FAST!
And NEVER, NEVER, AND NEVER
use that code on final project.
NEVER

12. Test a lot

40. prefer performance
rather than graphs

41. You can check the
device and change your
graphics configuration

42. //SystemInfo.deviceModel ->samsung SM - G925I
//SystemInfo.graphicsDeviceName -> Mali-T760
//SystemInfo.graphicsDeviceVendor -> ARM
if(SystemInfo.graphicsDeviceName.Contains("Mali"))
{
ChangeSceneSetup();
}

43. Different scenes
with different graphics
with different setups,
right?

44. GPU / CPU Level
Throttling

46. [DllImport("OculusPlugin")]
private static extern void OVR_VrModeParms_SetCpuLevel(int cpuLevel);
[DllImport("OculusPlugin")]
private static extern void OVR_VrModeParms_SetGpuLevel(int gpuLevel);
[DllImport("OculusPlugin")]
private static extern void OVR_TW_SetMinimumVsyncs(OVRTimeWarpUtils.VsyncMode mode);
OVR_VrModeParms_SetCpuLevel(3);
OVR_VrModeParms_SetGpuLevel(1);
OVR_TW_SetMinimumVsyncs(OVRTimeWarpUtils.VsyncMode.VSYNC_60FPS);

47. Signing Builds for
gear VR

48. Device id or imei
Abd devices
Assets/Plugins/Android/assets/<id>.sig

49. Signing Builds for VR
after APK is done

50. Add your sign file into
Assets folder

51. steps
Delete meta-inf folder

52. jarsigner -keystore <keystore_name>.keystore -signedjar <Build_Name_Signed>.apk
<Build_Name>.apk <alias_name>
jarsigner -keystore debug.keystore -signedjar FM_DEMO_VR_16032015_sign.apk
FM_DEMO_VR_16032015.apk androiddebugkey

53. Debugging on Gear
VR

54. Debug WiFi

55. ADB WiFi Connection
adb tcpip 5555
adb connect <device_ip_address>:5555
ex:
adb connect 192.186.0.101:5555

56. ADB WiFi Unity
Connection

57. I don’t have WiFi!

58. Gear VR
Develop ModeApplication Manager -> All -> GearVR
Service -> Manage Storage and tap VR
Service Version 7 times

62. “If you’re not optimizing for
the game’s bottleneck then
you’re wasting time”Phil Lira, Staff Eng.

63. Loading Time

64. Texture compression settings

65. Texture compression settings
If the device doesn’t support your texture compression,
Unity will decompress all textures before splash
Disable autoconnect Profile if
you are debugging loading time

66. DrawCall/SetPass

67. Unity 4 Unity 5

68. Conclusion

69. Immersion
Optimization starts on the first day
Always prototype and test a lot
Feedback as much as you can
And you should test Finding Monsters Adventure VR
and Rococo VR :)
