Hi, I am currently using a .env file for my scene which I generated a month ago (using the babylon sandbox export), but, now I want to change the environment to another one to get a better lighting quality.  
When I export a new .env file using the babylon sandbox (following the same previous process) I am getting an error that prevents it from loading.  
I used .HDR images in both processes and I don’t understand why am I getting that error.  
Any help would be really appreciated, thanks!

This is the error message:

Uncaught Error: Unsupported babylon environment map version “2”

This is a version mismatch problem, we’ve had some previous questions with the same issue:

[Error: Unsupported babylon environment map version “2” - Questions - Babylon.js (babylonjs.com)](https://forum.babylonjs.com/t/error-unsupported-babylon-environment-map-version-2/25155/3)

[.env conversion from .hdr throws an error - Questions - Babylon.js (babylonjs.com)](https://forum.babylonjs.com/t/env-conversion-from-hdr-throws-an-error/24762)

Sandbox now uses preview version 5.0, and your scene is probably using 4.2 🙂 Updating the scene to 5.0 is the recommended approach, since it’s backwards compatible and you get some improvements for free!

Hi @brainwilder just checking in, were you able to update your scene? 🙂
