Eye tracker 4C-Unexpected token usertype on viewDir in Surface shader of unity

[Supriya Raul]

Hello, I am using TobiiUnitySDKForDesktop_4.0.0 (for Tobii Eye Tracker 4C) with Unity 5.6.3f1 and I am able to get the screen coordinates of the gaze point. The thing I can not achieve is – “to make the object glow when the user gaze at it”. I am trying to make a surface shader and it’s giving me an error “Unexpected token usertype. Expected : identifier” on the float3 viewDir. Could you please help me identify what is going wrong with it?

Thanks in advance.

Hi @supriya!

You probably have an error in the shader you use.
We have a sample glow/outline shader and sample code in Demo scenes/First person

Thank you for your quick response Alex.
I could not find a shader with this name(glow or outline shader) in the package. Does it have some other name?

Thanks
