  1. Hi @GestureLab@VIVE_Jason_Lu, I am using Unreal 4.23.1 (VRS modified version), and SRanipal 1.3.3.0. I have also tried with SRanipal 1.3.6.8 and 1.3.6.6. All have the same problem, the gaze position is not moving, it is fixed at the center of the screen. Otherwise, the eye calibration and sranipal runtime are working fine. I am using win10 OS. Also, changed `SRanipal.uplugin` "Installed": false to "Installed": true as suggested here. No effect.
  2. From Marios Bikos' [Blog](https://forum.htc.com/topic/7434-getting-started-with-vrs-foveated-rendering-using-htc-vive-pro-eye-unreal-engine/#comment-32451), I am working with Variable Rate Shading, with the vive unreal 4.23.1, sranipal 1.3.6.6. Calibration, sranipal runtime everything is working fine. But I cannot see the eye tracking working in the project. It is now a static VRS. I have followed all instructions carefully. Please help.
  3. I have resolved all the previously posted issues. I want to delete the post, but I am unable. Could the page administrator please take action?
  4. @ArAnish, did you mean .uproject file? I tried this, but getting the same error message as this question mentioned, any solution?
  5. In connection with my question, cannot I build the unreal engine while the sranipal is in the source plugins folder `C:\UnrealEngine\Engine\Plugins`? While I was trying this: the output build messages were with error message: Severity Code Description Project File Line Suppression State Error MSB3075 The command "..\..\Build\BatchFiles\Build.bat -Target="UE4Editor Win64 Development" -Target="ShaderCompileWorker Win64 Development -Quiet" -WaitMutex -FromMsBuild" exited with code 5.

  6. Hi! I am following @MariosBikos VRS tutorial on unreal 4.24.2 source code version. I have already steamvr, sranipal runtime, and calibration done. After building the unreal source code I am creating a new project: Games >> Virtual Reality>> Blueprint (cannot see the C++ option). I am pasting the sranipal SDK v1.3.6.8 in the project folder under Plugins/SRanipal Before that, I have modified the SRanipal.Build.cs /* PublicIncludePaths.AddRange( new string[] { Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipal/Public" // ... add public include paths required here ... } ); PrivateIncludePaths.AddRange( new string[] { ModuleDirectory+"/Private", ModuleDirectory+"/Public/Eye", ModuleDirectory+"/Public/Lip", Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalEye/Public", Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalLip/Public" // ... add other private include paths required here ... } ); */ PublicIncludePaths.Add(Path.Combine(ModuleDirectory,"Public/Eye")); PublicIncludePaths.Add(Path.Combine(ModuleDirectory,"Public/Lip")); PrivateIncludePaths.Add(Path.Combine(ModuleDirectory,"Private/Eye")); However, while in the project, I cannot see the sranipal plugin under edit>> plugin>> project. while I am trying to reopen the project, I am getting the following error message and the project fails to reopen: Could you please assist me in solving the problem to enable eye tracking?
  7. I have a few questions for clarification: 1. I have cloned the 4.24.2. Instead of some minor errors, the UE is launching. In part 1, (8) to launch the UE, do I always have to follow the step: Open the .sln, then Debug > Start New Instance? Or is there any other way that I can directly run UE like a normal installation? 2. Part 2: 12, 13, 15: I have downloaded SRanipal v1.3.6.6. Extracting the .zip file includes Plugins\SRanipal. I am copy-pasting this plugins folder in a new project under a different directory than the unreal engine cloned (C:\ directory). But in Edit> Plugins, I cannot see the SRanipal plugin. C:\Users\local-admin\Downloads\unity\SDK-v1.3.6.6\SDK-v1.3.6.6\SDK\03_Unreal\Vive-SRanipal-Unreal-Plugin.zip 3. Part 2: 14, I do not see an error in Dartboard.h. But if someone has a problem, did you mean editing SRanipal.Build.cs as follows: PublicIncludePaths.AddRange( new string[] { //Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipal/Public" // ... add public include paths required here ... // from tutorial PublicIncludePaths.Add(Path.Combine(ModuleDirectory, "Public/Eye")); //PublicIncludePaths.Add(Path.Combine(ModuleDirectory, "Public/Lip")); } ); PrivateIncludePaths.AddRange( new string[] { ModuleDirectory+"/Private", ModuleDirectory+"/Public/Eye", ModuleDirectory+"/Public/Lip", Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalEye/Public", Path.GetFullPath(Path.Combine(ModuleDirectory, ".."))+"/SRanipalLip/Public"; // ... add other private include paths required here ... // from tutorial PrivateIncludePaths.Add(Path.Combine(ModuleDirectory, "Private/Eye")); //PrivateIncludePaths.Add(Path.Combine(ModuleDirectory, "Private/Lip")); } ); 4. Reopening the project returns an error as the image:
  8. Is there any confirmation from the Vive official? I also need the average luminance value for my calculation.
  9. I do not why the Vive developer forum is so cold? There is hardly any conversation found or solution. However, SRanipal does not have support for Linux what I found. Now question is, what is Vive's suggestion for XR developers to access real-time eye tracking?
  10. @HackPerception, I have previously contacted Tobii for support, they mentioned could not support for Vive pro eye headset.
  11. Hello Everyone, I am a newbie in this topic. I have just started with Linux (Ubuntu 20.04.4) and found there is no SRanipal Runtime for Linux. I am using `HTC Vive Pro Eye` and previously once I talked with Tobii, and they mentioned their SDK is not working for Vive Pro Eye. If you guys give me some solution to access real-time eye tracking data same as I could access in Windows (SRanipal+SteamVR)?
  12. Hello, I just switched to Linux (Ubuntu), and am trying to find SRanipal runtime for my SteamVR. Does `SRanipal` only work in windows machine? Is there no support for Linux? If so, is there any alternative eye tracking runtime software? I am using VIVE Pro Eye.
