Vuforia Unity extension for openGl es 1.x

June 22, 2012 - 12:04am #1

When we tried building a Unity Vuforia project for iOS openGl es 1.x it crashed. This does not happen with openGl ES 2.0.
Does the Unity Vuforia extension work with OpenGl ES 1.x?

* see my correction above - I was thinking of the native SDK.


Yes it does. Was this project originally a 2.0 that you later changed to 1.1 in Unity? If so, you may want to try with a fresh project.

My mistake. The iOS Unity extension does NOT support 1.1. You'll need to build for 2.0.

From the getting started guide:

"Also ensure that Target Platform is not set to armv6 (OpenGL ES 1.1). This version of the extension only supports OpenGL-ES 2.0."

See the iOS Deployment Process section here - https://ar.qualcomm.at/qdevnet/sdk/ios/Compiling%20a%20Simple%20Project
