Prompt:

"HDRI Panorama View of some nice room..."

Use correct ratio:

• Equirectangular: 2:1, so like 1024x512 (less is also ok, more coherence on 768x512)
• Polyhedron net (cubemap tiled): 4:3, like 1024x768

Click on Pano-Button once to get the panorama viewer, and click again to close the panorama viewer and switch back to the original gallery view.

Convert into Cubemap inside the gallery

And send to openOutpaint for finishing
