I just tried ProEXR 2 that now handle cryptomatte ( I use it in conjunction with C4DtoA )
I was used to classic merged EXR unpacking using ProEXR and it worked like a charm in AE,
and tried the cryptomatte version, It works but I find cryptomatte awfully long to unpack (like around 10 seconds per frame, which is really long compared to classic EXR which unpack instantly)
does anyone have the same issue ? is it normal ?
