just a cubic burning ship rendered with KF pre-release WIP version (to be released maybe end of next week, need to add one more feature...), exported as half-precision float RGB EXR at 6400x3600 and post processed in a lightly patched* version of darktable to make the colours much nicer.

(*) darktable mainline can't load EXR with additional channels (KF save N and NF iteration counts too, and DE if derivatives were calculated), I have a pull-request that makes it ignore anything apart from RGB(A). EDIT pull request merged, 2.8 milestone.

PNG export may have less banding (I think the JPEG suffers from YUV/RGB conversion quantization, but I may be imagining it)

compared with how it looked in KF before export, I think darktable is quite powerful
