Can't open hdri in Blender 2.8 release candidate do you also have issue with opening HDRI in Blender 2.8 release candidate? Did something changed?
My approach is to go to the world settings, change color to an environment texture, click to open texture, but all HDRIs are invisible for Blender. I tried switch off filters or move HDRI directly to the world window, but nothing happens. I checked also addons, did I miss something?
You've probably accidentally removed image files from the filtering in the file browser. Make sure that when filtering is turned on that the image icon is also enabled. Otherwise it won't display image files.
