Wondering if one of the Foundry folks might be able to answer why there is
a from/minus layer mode in the roto node when it ends up creating negative
values (something you never want in an alpha). It's been like this forever
and I'd rather have mask/stencil modes available. Coming from Shake
Hi John
To give you a non answer. Fortunately or unfortunately with all our tools
we give you enough rope to hang yourself with. None of our tools hide
anything from the user and do the same math in the roto node that the merge
node. As you mentioned though we should probably have something
Keep in mind that those same blending modes apply to paint strokes as well,
where there may actually be a reason to use straight subtraction.

Hi John
Hi all,
In Nuke 7, I am able to copy and paste a path containing .3dl file like
this ~~/lut/001/MYSHOT_lut_v001.3dl and it would automatically paste as a
('Vectorfield') node with the ['vfield_file'] filed in for me.
In nuke 8, it doesn't do that anymore?
Woei
Nuke doesn't do this by default. You probably had JOps installed in Nuke 7
which adds this ability.
J_Ops also bundles utility python scripts, as well as adding a preferences
tab to allow easy configuration. The scripts include:
Improved drag and drop - create geo nodes when dropping
I have used roto in the past to work on data channels such as motion
vectors, in which case negative values are quite important.
It's more of an educational problem than a software feature problem
I think, but I guess a clamp option might be a reasonable thing to
Good to know!
Thanks! Deke!
