Hi Hugo, thanks for this nice demo!

Would it be possible to export HDR images?

https://docs.godotengine.org/en/stable/tutorials/3d/high_dynamic_range.html states:

For advanced users, it is still possible to get a non-tonemapped image of the viewport with full HDR data, which can then be saved to an OpenEXR file.

How can this be achieved? It would be really interesting for my workflow.

This should be possible by doing 3 things:

Enable HDR 2D on all Viewport nodes in the create_example_cubemap.tscn scene.
Enable HDR 2D on the root Viewport in the project settings.
Replace the save_png() calls in https://github.com/Calinou/godot-cubemap-generator/blob/main/save_image.gd with save_exr().

Make sure to stick to the Forward+ rendering method when doing so to ensure the maximum possible color precision.
