Hi Frank, Nice to meet you mate. I'm aware of the auto label functionality and channel indicators in Nuke but reading the channels a node is affecting on its label or indicators isn't the same as figuring out what that node is actually doing, hence the request for a Roto only node at that time. It's faster to recognize what is shape/roto only from what could be or include painting which tends to bog down scripts.
Back in the day Nuke was moving from a Bezier node where we had a single shape per node and a alpha version of a Paint only node that was far from great, to a "do it all" RotoPaint node. People felt divided and the solution came in the form of a streamlined Roto only version of the RotoPaint that was introduced into Nuke 6.1. My point was that for what I know there should be no difference between the two in terms of performance or functionality while talking exclusively about shapes (bezier, b-spline, open splines) since they are the same and share the same bits of code. As for performance, I think it's fair to say that the fewer channels a Node > operates on the faster that Node will be. I would say it's more than fair, it's pretty much a certainty :) Cheers, Diogo On Sat, Apr 18, 2015 at 5:17 AM, Frank Harrison <fr...@thefoundry.co.uk> wrote: > Hey > > On 1 April 2015 at 17:04, Daniel Hartlehnert <dah...@gmx.de> wrote: > >> Because it also means to constantly click in the viewer before pressing >> "A" to make sure it has the focus. >> > You don't need to click in the viewer, just have the mouse hovering over > it. > > > On 18 April 2015 at 05:55, Diogo Girondi <diogogiro...@gmail.com> wrote: > >> since you can't actually differentiate what is purely masks from what is >> paint or both. > > Just in case you weren't aware, the channels affected are rendered on the > Nodes in the DAG.
