Thanks a bunch for the info!
Honestly, the jargon surpassed my limited programming skills by a lot, but I have forwarded your advice to the Neurosity developers who may be able to make use of this info to create a proper SDK for their EEG device to interface with Unreal… eventually.
And, yes, I found integrating the Node.js code to be extremely painful and unsustainable. The neurogame template I made only works in one machine and I don’t know why. So, I just gave up on the project altogether. I am now trying my luck with Unity and a third-party SDK. It is not game dev friendly either… X-D
