Y.A.H.A stands out in the Blender extensions library for pulling HDRI browsing, colour grading, background modes and sun lamp alignment into one panel instead of the node editor.
Y.A.H.A, short for Yet Another HDRI Addon, is a Blender add-on from ArtinŌr built as a modular hub for the HDRI workflow. It handles browsing and previewing HDRIs with thumbnails, and keeps its controls in a single panel rather than the node editor or nested menus.
Beyond browsing, the add-on offers full colour grading with temperature, tint, gamma, saturation and contrast, plus multiple background modes: original, blurred, solid, gradient and custom. You can save favourites per project or globally, and use sun lamp alignment and colour matching, all from the same panel.
Version 1.0.1 works with Blender 5.0 and newer and is distributed under the GNU General Public License v3.0 or later. This release removed load handlers and timers so nothing runs on startup, merged operators that set the same property into single ops, and switched to extension_path_user with a ~/.config fallback instead of writing to the add-on directory. It requests file access to scan local folders for thumbnails and environment mapping.
Y.A.H.A is best for blender artists who want to browse, grade and manage HDRI environment lighting from a single panel.
Y.A.H.A is completely free to download and use.
Y.A.H.A is compatible with Blender 5.0 and newer. Version 1.0.1 dropped bl_info because the add-on targets Blender 5.x and later only, and it removed load handlers and timers so nothing runs on startup. If you are on an earlier Blender release, this version will not be available to you. For the current version history and any further compatibility details, the developer's page on projects.blender.org is the place to check before installing.
Y.A.H.A installs through Blender's extension system. You can drag and drop the add-on into Blender, or download it and use Install from Disk in the preferences. Once enabled, its controls live in a single panel rather than the node editor. In version 1.0.1 the add-on no longer writes to the add-on directory, using extension_path_user with a ~/.config fallback, and keymap entries are now set from Blender's keymap preferences rather than through a bundled keymap operator.
Y.A.H.A requests file access as part of its permissions. It scans local folders to generate thumbnails and map environments, which is how the browse-and-preview workflow builds its HDRI thumbnails. This permission is what lets you point the add-on at your own HDRI collection on disk. For full details on the permission and how folder scanning works, the developer's page on projects.blender.org is the best reference.
Y.A.H.A is listed as free in this catalog and is distributed under the GNU General Public License v3.0 or later. For the current licensing terms and any changes, the developer's page on projects.blender.org is the best reference. The add-on is provided by ArtinŌr through the Blender extensions platform, where you can also find its version history and report issues if you run into a problem.
