I used Crytomatte on Katana, and it did not export cryto_object00,cryto_object01,cryto_object02 channels.So it can't be used on Nuke.Can you give me some way to use it.
This is not Katana or Arnold problem but need to fix from Anders Langlands who build alShader, from his answer he said he never use Katana before it mean have no idea.
After Arnold 5 update I saw here work well in maya but not for katana.
my problem not only CrytoMatte but I can't render EXR multipass images after update to Arnold 5.
