Bump.

When I use the Focus node (image 1), the eye tracking seems to work (image 2). My problem is that the Focus node only returns the hit actor. I need it to return the component(s) within the actor. This can be done with a Line Trace node, so I used the gaze origin and gaze target to set up a line trace (image 3), but I'm having trouble getting it to work (image 4). I know it's user error because the Focus node works. I just can't wrap my head around how to connect the Gaze information nodes to feed the Line Trace node. Any help on how one goes about setting up the Line Trac

This documentation is completely lacking when it comes to focus and gaze information. The first 5 pages is setup. Then there is only one sentence that refers to the player's focus. Then the next 5 pages are regarding avatar morphs. So if you want to do anything other than make an avatar blink, you're on your own.

SRanipal version: 1.3.2.0, Unreal Engine version: 4.26.1, Headset: VIVE Pro Eye. If I set the Project Settings to Enable Eye by Default (Image 1), and then set a basic blueprint to print some data (Image 2), it works fine (Image 3). But if I turn off the Enable Eye by Default in the Project Settings and then try to start it using the Start Eye Framework node (Image 4), it doesn't seem to work (Image 5). What's weird is that the Get Gaze Data node is still returning "True", but the actual data seems to be frozen (Image 5 again). I assume it's user error so any tips would be

So if I just wanted the gaze information, I shouldn't bother with Version 2, correct?

Sorry if this is a repeat, I looked through the forum and didn't see this asked. I'm using SRanipal SDK in Unreal. When I start the Eye Framework, I can choose between Version 1 and Version 2. Wondering if someone can tell me the difference. Thanks.

I believe you calibrate the headset in the SteamVR menu, not in UE. Press the systems menu button below the trackpad to open the SteamVR menu. Then select the VIVE Pro Eye button in the lower part and select calibrate. This should run you through the calibration process where you follow the little blue dot with your eye. Hope that helps.
