I'm working on an outer space scene with a HDRi star texture and while I'm happy with the sun settings (direction, intensity, angle), I'm trying to figure out if there is a way to make the sun disk itself visible.

A Google search results in a link to the Blender manual, but there's nothing in there regarding the sun disk itself. https://docs.blender.org/manual/en/latest/addons/lighting/sun_position.html

Can the sun disk be made visible? or is there a workaround? Thanks. Blender 3.01, Windows 11

    $\begingroup$ no you can't, you need to use another object like a sphere or a circle, and give it an Emission node $\endgroup$

  • $\begingroup$ @moonboots Thank you! Another question: Is there a quick way to align an object to the sun's position? Or is that a trial & error process? $\endgroup$

    $\begingroup$ if you want to put it at the same position, select the sun object, then Shift S > Cursor to Selected, select the sphere you've created and Shift S again > Selection to 3D Cursor, but actually the sun location doesn't count so I'm not sure what you mean $\endgroup$

    $\begingroup$ As I said, if you're talking about the sun object itself, contrary to, for example, a point light, its location doesn't count, only the rotation (and all the parameters you'll find in the Object Data panel of course). You can place the sun wherever you want in the scene, it's considered to be infinitely far away, and its rays are parallel $\endgroup$

    $\begingroup$ You could also make a sun part of the HDRI image, this way it will always look far away $\endgroup$

You can't make a light visible as an object in render, you need to use another object like a sphere or a circle, and give it an Emission node.
