I want to remove all the skipping frame message from ray output, using -message option but do not succeed.

i want to hide :

MI 0.0 info : skipping frame 76, deselected by -render
MI 0.0 info : skipping frame 77, deselected by -render
...
( eventually API class as well )

using -v 3 removes, but also remove all the other logs, would be good to say : -v 3 -message RC all --

thanks, shangu
