Hi Christopher, thanks for the link. I have only built OpenEXR when building blender ('these packages' really refers to the unpleasant mess of cmake and python packages pulled in for blender). I had built it on three machines in February, only one hit this problem. I then built it on two or three machines in September, that was extremely aggravating (not for OpenEXR) and at the end of the day I don't think that using a home 3D printer is going to be practical for me for what I was thinking about. And rendering the files - even on my machine which now has more than 30GB available for 8 CPUs - is still horrendously slow. But along the way I tried one 'movie' demo which created exr files - I thought I could look at them in 'iv' from one of the blender dependencies, but they seemed to not look at all like what I was expecting. ĸen -- The people next door oppress me all night long. I tell them: I work all day, a man's got to have some time to learn to play the tuba. That's oppression, that is. [ Guards!
