I found several tutorials explaining how to set up an HDR image as light source. Now I would like to shift the map around and view the results at the same time.
Other 3d software show a sphere with the environment mapped to the inner side. Lighting is updated according to orientation of the map.
Thank you for the comment. It may be a noob problem but I don’t know how to make the AngMap visible in the viewports. I would like to have the effects of shifting objects or environment displayed while I am rotating. The purpose is to align the HDR sun with blender light and see a preview of reflections on materials in the scene.
