Panorama to Cubemap (jaxry.github.io)

Eight corners can be clearly seen in the panorama converted by Panorama to Cubemap (jaxry.github.io) .
The transition is not very smooth

    skyboxMaterial.reflectionTexture = new BABYLON.CubeTexture("textures/TropicalSunnyDay", scene);
    skyboxMaterial.reflectionTexture.coordinatesMode = BABYLON.Texture.SKYBOX_MODE;

From the code comments here, it seems to be inverse cubic: Babylon.js/texture.ts at master · BabylonJS/Babylon.js (github.com)

you should be able to use coordinate mode FIXED_EQUIRECTANGULAR_MIRRORED_MODE with a 360 picture.

I have re implemented the conversion function locally through Electron, and now the display of the Sky Box is normal
