why would you have negative RGB values in a linear pipe?
there are many Nuke nodes that will clip at 0, especially mergers. I think you need to take a look at what your colour conversion to linear is doing. the only time I would expect to see negative values would be in secondary channels like pWorld or maybe zDepth and generally speaking the only thing I would use a grade node for is to maybe normalise depth. ----------------------- Tahl Niran vfx compositor www.tahlniran.com Date: Thu, 21 Apr 2011 11:19:15 -0400 Subject: Re: [Nuke-users] Grade clamping From: [email protected] To: [email protected] the reason is in alpha channel - matte. _______________________________________________ Nuke-users mailing list [email protected] http://support.thefoundry.co.uk/cgi-bin/mailman/listinfo/nuke-users
