I have already solved this problem In addition to Meters Per Unit, it is also necessary to set the Cube Primitive property

I know that preparing multiple .skybox folders in the project ahead of time can dynamically change the ImageBasedLight during runtime. But my entire scene usdz is downloaded from the url, so my HDR picture is also downloaded from the url. How to turn the HDR image downloaded in the URL into an EnvironmentResoure and then generate an ImageBasedLightComponent Thank you very mush
