Hi Gabor, Personnaly i render unfiltered double res ppass and downsize the result to generate antialiasing. It's not perfect but make the deal for so many cases. I suppose this can also be handled with a coverage pass and thus perfect results, but i had never did it. cheers philhub

I use these for years now, but I always wanted to ask, how do you treat the edges? What type of positionpass do you use? I use filtered and also unfiltered, but when I create the mask, especially when selecting an area in front a of another area further away, I always have to hack the edges with erodes/rotos etc. Does anyone have a method that lets user select the desired area and somehow finetune the motionblurred edges without any hack like this? Or is there a special difference pass that can be outputted from 3d render, and helps in this situation? I mean when rendering to separate layers is not an option, and without deep samples. Any help appreciated, thanks Gabor _______________________________________________ Nuke-users mailing list Nuke-users@support.thefoundry.co.uk, http://forums.thefoundry.co.uk/ http://support.thefoundry.co.uk/cgi-bin/mailman/listinfo/nuke-users _______________________________________________ Nuke-users mailing list Nuke-users@support.thefoundry.co.uk, http://forums.thefoundry.co.uk/ http://support.thefoundry.co.uk/cgi-bin/mailman/listinfo/nuke-users
