That’s unfortunate. Are you seeing a black screen in the app itself, or when you launch your game?
DUCT was designed for a much older version of EFPSE. I had a revised version in the works that was ported over to Stride3D, but dropped that version when EFPSE-CE added official support for image streams with an in-house tool to package your videos. I’m willing to look into this and I can update either the new or legacy version of DUCT to fit your needs if necessary.
