mask option for individual footage node in nuke?

[pamulighter]

hi friends ..
any one can tell me how we use matte for individual footage node in nuke?
we have mask option in fusion for individual footage node, we can connect mask directly to the footage or any or other node ...
but in nuke that i don't know ..
is there any different method ?

There are lots of ways of using mattes in Nuke.
The old school way by pluggin a matte directly in the side of a node.
The more modern way of using a matte that is already in you stream with de Matte option in any node.
And of course the manual way of using merge nodes.
These kind of questions are all answered in the nuke manual.

It is not possible to connect a mask in to a read node directly in Nuke like you do in Fusion.
Instead use a 'copy node' to copy your mask in to read node's alpha channel and then add a pre-multiply node.
It should mask out the selection.

It is worth to take a look at these tutorials to get a basic idea of Nuke's workflow.
