I am using an HDR to light my world in a .blend file. It works fine normally, but when I pack it it mysteriously goes missing during render time. Why is this?

Here is a .blend file demonstrating it: http://www.pasteall.org/blend/37691

Notice how you can unpack the HDR and it loads fine in the UV Editor, but rendering it's gone!

  • $\begingroup$ Your example file worked just fine for me when rendering. Maybe try it again? $\endgroup$ – Nathan Aug 22 '15 at 2:44
  • $\begingroup$ No, doesn't work for me. Could you see the HDR, or did everything turn out pink? $\endgroup$ – LiquidHelix Aug 22 '15 at 17:34
  • $\begingroup$ I could see the HDR image. No pink. i.imgur.com/xeyCuJ1.png?1 $\endgroup$ – Nathan Aug 22 '15 at 18:26
  • $\begingroup$ Could it be a problem with my computer? I always seem to get random problems no one else does. $\endgroup$ – LiquidHelix Aug 22 '15 at 20:49
  • $\begingroup$ Try opening a new blender file, switch to cycles, open an HDR for your environment lighting, and pack it. Let me know if that works. $\endgroup$ – Nathan Aug 23 '15 at 15:28

The problem was solved when I switched to the CPU renderer. I am guessing that OpenCL is at fault, because it happened during GPU rendering. More information here.

Looks like GPU OpenCL is lacking many features, so I recommend using CPU renderer for now.


In the Render View window, select Display > Color Management... The viewColorManager Attribute Editor appears. Select the color profile for your image source and your display output using the Image Color Profile and Display Color Profile drop-down menus. Specify your custom calibration file or color transformation file in the LUT file attribute. You can also use this attribute to apply a color grading effect. What editor are you use? try out aurora Is it mac or win?
