Ben's Comp Newsletter: Issue 037
|
|
Hey,
In this week's newsletter, we're taking a
look at some handy utilities to make your
Compositing workflow a little less
frustrating, and looking at some of the
upcoming technological developments being
showcased at Siggraph this year.

Inverse-Kinematics in Nuke
Johannes
Masanz has
created an example Nuke script which
demonstrates how a simple IK rig can be
achieved in Nuke. At first, this just
seems like a fun little example,
although there are actually a lot of
practical uses for this!
Using Chappie
as an example, there were a lot of shots
where Die Antwoord would touch/grab/push
Chappie, and vice versa. Some of the
decisions made on set meant that these
interactions looked incredibly realistic and
gave matchmove & animation so much
information & real-world reference to
match to, although Compositors always have
to bring that next level of sub-pixel
accuracy.
There were plenty of shots I composited in
the film where Chappie would grab a plate
character, and I would need to warp elements
of said plate to make it look like things
were interacting in a life-like way. If I
had this IK tool at my disposal when doing
these shots, there would have been
significantly fewer hours spent noodling a
GridWarp or SplineWarp to do the right
thing!
Johannes has created a demo
video which you can watch
here.

Rename Channels
Every
studio has its own naming
conventions for what they render and
how they name AOVs. For larger,
complex shots with many renders and
many more sets of AOVs for those
renders, things can get pretty
cluttered and slow to work with.
Part of this frustration comes from
trying to find the channel you need
in a big list of AOVs named
something
like, lgt_character3_noholdout_indirectspecular_denoised,
as an extreme example.
Andrea
Geremia has
created a neat little solution for
this problem, which helps you rename
channels into clean,
Compositor-friendly names. The
Foundry already has a
way of doing this, although
as Andrea mentions in his
description on Nukepedia, it can be
buggy and
unpredictable.

Reduce Noise Like A Pro
In the
following video, Lars
Wemmje explains
how to properly use Reduce Noise to
denoise your plates! If you've ever
wanted to dive into Neat Video's
Advanced Mode to make the most out
of your denoise, this video tutorial
is for you!

Siggraph 2019 Whitepapers
I found this list that links to all of this
years' Siggraph papers. Enjoy an early sneak
peek of what's to come!
A couple of my favourites are about Synthetic
Defocus, Mocap
from a monocular video source, Single-image
portrait relighting, and Local
light field fusion being used
to reconstruct a scene -- like
projection-mapping but with accurate
reflections.
