Hello Alexander,

Which version of unreal are you using?
Did you try to start the project from the .uproject file?
Did you got the plugin inside the Plugin folder on your Project directory?
First time running the project with tobii, or did you get to make it work before?

Any other detail that you can think of would be helpfull to see if i can help you,

Hello Leandro,
First,
a) I made new UE 4.21.2 c++ project in UE Launcher.
b) Add Plugins\TobiiEyetracking folders and unpack Tobii_UE4SDK_4.21.0.151.zip into that folder
c) regenerate UE project files
d) compile solution as develper editor
e) run from VS – got an error
f) run from .uproject – got an UE crash
Second,
a) I made new UE 4.21.2 BP project in UE Launcher.
b) Add Plugins\TobiiEyetracking folders and unpack Tobii_UE4SDK_4.21.0.151.zip into that folder
c) run from .uproject – got an UE crash

I use Vive pro eye

I don’t see a possibility to attach picture, therefore I try to post link for screenshot from VS with aforementioned error: “https://drive.google.com/file/d/1EoUbyPKOnMBElfPA-L5glV86HislOQg_/view?usp=sharing”.
This shot was captured on DebugGameEditor configuration run.
Additionally, before I try to use Tobii UE4 plugin, I’d install a core software from Tobii_Eye_Tracking_Core_v2.16.4.67_x86.

Hello there guys!

I’m the principal developer on the UE4 SDK.
I tried to repro this, but I don’t seem to be able to. Would you be willing to give me some more info on how I can suss this problem out?
The best way to get a hold of me would be to contact me on our discord https://discord.gg/QMnscrj

I’m “Temaran” on there.

Thanks!

Hello!

An update on this issue. It right now seems like the g2om binary requires the CPU to support AVX2 which caused the crash in this case.
I’m going to see if I can get a new version that addresses this up in the near future, but I cannot unfortunately promise anything.

For now, if you reading this are encountering this issue, please contact me on discord and I can attempt to help you.
