I just tried hdri maps. I’m watching the tutorial of andrew on blender guru.
I download a free hdri map (studio type). it works just fine except the image is not showing in the view port like the on the tutorial where in the image wraps around as a background. or is it a different type of HDRI used in the tutorial?

Ensure you are in perspective and not orthographic view (Numpad 5)
