Hello! I started testing your program today and ran into some problems with green screen footage being incorporated into the scene view(GS footage has checkered background). I'm putting in my unreal scene with DE and I went through the youtube tutorials but still the issue persists. Here are the screen shots of my settings.
Thanks!
The checkered background is displayed, because you probably selected the CAM1 mode for preview.
Use the PROGRAM mode instead.
But there's another issue. From the log it seems that there's some problem with the Aximmetry_Camera asset in your scene.
Please remove the Aximmetry_Camera object from the scene, delete the asset files form your project folder, replace it with the newest version from Common_Studio, then readd the Aximmetry_Camera blueprint.
Then recook the scene and try again.
