Hi Gonzalo,
I haven't been able to check the file but I assume it contains one
deep part and one regular image part for the beauty. EXRs are slow if
the data for parts is interleaved - when the file was written, Arnold
possibly alternated between writing scanlines of deep and scanlines of
regular image; reading back the beauty picture might require a skip
every scanline, which can be quite time consuming.
Try running "exrstdattr input.exr output.exr" (no extra arguments
required) and see if output.exr is faster
Hi, Peter.
Your analysis is what I suspected, but using exrstdattr did not make any
difference. The output file is still slow to load the beauty picture.
I have no way of finding out whether the beauty and the deep data are
interleaved or not.
Thanks for the help,
