Hi Alex,
Thanks for your kind words and for giving it a try. I'm not sure why it wouldn't work on an AMD, my suspicion is it's to do with the Gaussian Splatting technology that requires RTX. Are you able to load the front end and see the text and just a black background?
I'll have a chat with the coder and also look into the requirements that the Unreal Plugin needed to see if that's the root cause.
Thanks for taking the time to try.
Peter
