[bubo3d]

Hi, i checked out Arnold 6.2 , its post tab has 2 bad problems.
1. when i add or remove an image corrector, progressive render starts render from the beginning.

2. when i stop render progress, image corrector in the post tab can't affect on render image

1. Is the expected current behavior.

2. Can you provide more details about the scene? Any errors in the log file?
