Screen-space mesh in Nuke.
Mark
Joey Tang has
figured out a neat way to create
geometry using position, depth or
deep data.
Watch the tool in action in this
demo video.

interviewed MJ early-2019. You

Quick Tip: Refine SmartVectors with an
STMap.
SmartVectors,
and the associated VectorDistort
node is one of the best new
additions to Nuke in recent years.
Being able to effortlessly track a
texture to an organically-moving
object is amazing when it works, but
oftentimes SmartVectors
only gets us part of the way
there and needs refinement...
By changing the
VectorDistort's Output
knob to "st-map",
we gain the ability to modify
SmartVectors in a bunch of
ways, before using an STMap
node to apply the modified warp
to the image (as you see in the
setup pictured). For example:
If a track slips off in a
section: Isolate the
problem area with a rotoshape, and
adjust the warp with an iTransform.
Blurring the rotoshape will give you
a nice, smooth transition between
the VectorDistort &
your extra warp!
If a track is slightly
jittery: Add a blur to
the problem area. Blurring the
st-map averages the pixels, and
therefore averages out the
motion.
If you want to blend between
two SmartVectors: You
can simply Dissolve between
the two st-maps!
Working with SmartVectors
this way adds an exponential
amount of extra power into an
already powerful tool. How else
could you utilize this
technique?

Love VFX: Mocha Pro for Nuke Tutorial.
Lars
Wemmje recently
reached out to share a cool tutorial
he made about the Mocha Pro OFX
plugin for Nuke. This
tutorial covers the basics of how to
do cleanup work, roto,
tracking/stabilizing &
undistorting lens grids using
Mocha.
Mocha is one of those tools every
Compositor should have in their
repertoire, as its a great companion
when Compositing in Nuke. If you've
never used it before, or haven't
opened it in a while, this tutorial
is for you!

Raytracing in... Excel?
I
love spreadsheets and use them in so
many ways, from tracking different
statistics, using them to plan
travel, organizing certain projects,
etc. Although, I never thought I'd
see it used to render an image.
Check out this video, and prepare to
have your mind
blown!
