Hi,

Spout plugin has been confirmed to work with RTX NVidia cards. In fact, this is what we used in this project:

Cheers,

Hi @meetya
thank you for replying btw amazing project it’s very impressive!
I’m currently using Spout Plugin on Unreal Engine from here: GitHub - AleDel/Spout-UE4: Spout Plugin for Unreal Engine to send the Viewport data to another application. The project has Ray Tracing and DirectX 12 enabled and If I try to start the app from editor It’s crashing. Could you give me some more info on how you handled the problem, if it’s possible…
Thank you!

Hi @Christian_Stamati,

I was having a similar crash with version 4.25.4 when I play with a new window. However, when I changed the play option to the ‘selected viewport’ it solved the crashing issue.

Hope it helps.
