Some ideas when this may be useful:\n- Adding a sun to a scene rendered by EEVEE, as EEVEE cannot render shadows from HDRI environment textures\n- Adding any light to enhance a scene, in alignment with direct light from the environment\n- Improve a panorama created with Google Streetview app for use as an environment texture in Blender, see the following excellent video by Blender Daily: [Easy HDRI Creation with just a Phone!](https://www.youtube.com/watch?v=Aco0UDxL6rA)\n- For a nice overview of the addon, see the following video by The CG Essentials: [Fixing Eevee HDRI Lighting](https://www.youtube.com/watch?v=J6ZufnYu0sI)\n\n# Blender Artists forum\nA discussion thread about this addon can be found on the Blender Artists discussion forum:\nhttps://blenderartists.org/t/hdri-sun-aligner-v1-4/1142638\n\n# Usage\n- Add a HDRI environment texture (equirectangular projection) to the World in Blender\n- HDRI Sun Aligner is accessed from the panel to the right:\n\n\u003ca href=\"https://imgur.com/7L8l0nS\"\u003e\u003cimg src=\"https://i.imgur.com/7L8l0nS.jpg\" height=\"200\" title=\"source: imgur.com\" /\u003e\u003c/a\u003e\n\n- Calculate the brightest point in the HDRI used for the environment by clicking on \"Calculate sun position\"\n- A preview of the calculated position can be displayed in a new window by clicking on \"Preview\":\n\n\u003ca href=\"https://imgur.com/nymkd3D\"\u003e\u003cimg src=\"https://i.imgur.com/nymkd3D.jpg\" height=\"200\" title=\"source: imgur.com\" /\u003e\u003c/a\u003e\n\n- Updated \"Longitude and Latitude\" values are displayed in the panel (can be changed manually)\n- Select any object and click \"Rotate object\" to align it with a vector from the calculated point to origo\n- To add a new sun (rotated in alignment with the current sun position), click \"Add new sun\"\n  - The new sun will be located in a new collection, \"HDRI Sun Aligner\"\n\n# Installation of HDRI Sun Aligner addon\n1. Download latest release from https://github.com/akej74/hdri-sun-aligner/releases (source as ZIP). \n2. Open Blender preferences -\u003e addons and select \"Install from file\"...\n3. Activate the addon, \"HDRI Sun Aligner\"\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fakej74%2Fhdri-sun-aligner","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fakej74%2Fhdri-sun-aligner","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fakej74%2Fhdri-sun-aligner/lists"}
