Hope you're having a productive
week. Here's your bi-weekly dose
of Nuke
knowledge!
DECONSTRUCTING
DESPILL
ALGORITHMS Despilling
is arguably the most important step
to get right when pulling a key.
You’re already aware that keyers
like Keylight, Primatte, IBK, etc.
despill your image, but what happens
if their results are coming up
short?
It’s absolutely worth your time to
dig into some basic maths &
understand how despill algorithms
work, and how you can implement them
into your workflow using the
Expression node. I
wrote an article about
5 different despill algorithms, and
how to work with them inside of
Nuke.
LAYER
SHUFFLER For those
who don't check Nukepedia often,
here's a brilliant new addition
from Kaloyan
Ganev that I'm quite
excited about! LayerShuffler breaks
out & automatically re-assembles
AOVs from a multi-channel EXR.
Whilst the concept of this isn't
new, some of the features he's added
are. These include:
Choosing
which render engine the AOVs
are from (which
significantly helps the
re-build process, rather
than the tool having to
guess &
making mistakes. VRay
& Arnold are the only
two render engines
currently supported)
Setting
your preferred node spacing
between AOVs
Choosing
the colour of the backdrop
nodes, which is incredibly
handy to have automated when
you're working with many
renders in one
shot
LOOPER Damian
Binder has created
a great tool that helps
seamlessly loop your elements!
I recently used it to prolong the
duration of the perfect atmospheric
dust element that was just too short
for the shot I wanted to use it
for. Check it out on
Nukepedia.
If
you've
created a
gizmo or
python
script to
solve a
common
problem or
speed up
your
workflow,
please reply
to this
email and
let me know
about it's
existence!
I'd love to
help spread
the word, to
help us all
be better
compositors
together!
