I will submit this finding to DxO but as the ‘problem’ doesn’t occur in PL6 I can’t see them going back and changing PL5.
It’s not a problem to me. I only stumbled across it when experimenting with using Adobe DCP profiles in PL. I wondered if one image I was looking at would benefit from the Warm Filter, except nothing changed when I applied it. I then tried the Mauve Filter in case the impact of the Warm filter was so subtle I was missing it but when still nothing changed…
Filters have no effect with a DCP rendering in PL 5.8 on both Windows or Mac for me.
DCP support in PL is fairly broken unless every computer you edit on has the dcp file at the same path since the absolute path is written into the dop file. Mac PL seems to deal with this better than Windows PL. On the Mac the rendering (and crop and maybe more) is silently discarded, but you can import the dcp at its Mac path to get back on track. Try to edit with the resulting dop on Windows and the result is “Internal Error (SetFromUserParams Failed)”.
Fairly unusable unless you want spend your time manually editing dop files.
