I am just starting to play with NX 2.0. So far, I like it (except that it keeps crashing on my notebook computer, which runs Windows XP Pro. It runs fine on my Vista desktop machine...)
The new Selection Control Points are a great addition.
I don't quite understand the purpose of the "Base Mask." I have Jason Odell's new eBook on NX 2.0, but I am still not getting it. It seems to select the entire image.
What is the Base Mask for?
Base Mask is a tool that allows you to fill the ENTIRE image with an effect at the opacity you desire. For example, let's say that you painted in saturation using the Selection Brush to part of the sky, using an opacity of 50%. Now, if you wanted to fill the remainder of the image at a lower opacity, instead of painting you could slide the base mask to 20% and you'd fill in the saturation effect everywhere else, too.
