Environment Brute Force is an add-on for Blender that helps find the optimal lighting for a scene by iterating through a number of environment images. You specify a directory of environment images, set a number of frames for each single image, enable brute forcing, and play the timeline animation. All environment images are then consistently applied to the scene, with every image rotated across its frame range to turn a full 360 degrees.
Rendering the animation (via Ctrl + F12) produces an image sequence of the scene lit by different environments at different rotation angles. Output file names are appended with the name of the currently used environment image and its current rotation angle, so you can search the resulting sequence for the best lighting and carry that choice into a final render.
The add-on ships with documentation and is listed as compatible with Blender versions 2.80 through 2.90. It is a Dev Fund contributor product, and a demo video is available for those who want to see more before installing.
