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.
