Hi imarin:
According to your symptom, perhaps the problem is on your framework GameObject setting.
The SRanipalEyeFramework game object has an option to choose enable which version's framework.
I have test with the latest SDK, the prefab's default enable version will be set to "Version1". So you can get proper value in original version eye framework.
You can checkout the "Enable Eye Version" first in the game object's inspector.
If it still not working, maybe you can check if our sample scene: EyeSample_v2 can works properly or not.
If the sample is not working either, please let me know. Thanks!
Best Regards,
Jason
