Getting an all green screen with messages No primary surface render node. No cameras in scene. The net effect is the same as the one @GitschiDev experienced in this thread. However I am not even importing any sprites. The scene only has a Unity brand Cube primitive with a random material from the Tiny3D demo. This cube sits in a little sub-scene. I just created a main scene, sub scene, and duped-out but functionally the exact same .asmdef + build configuration settings as the Tiny3D stuff in the project. The Tiny3D stuff still builds and runs fine. But the stuff I added does not. I even tried adding the AutoMovingDirectionalLight.cs component to the light in my new main scene to see if it was somehow pulling in a camera making the Tiny3D build work. This happens for a WASM and Windows il2cpp build.
