Screen-space mesh in Nuke.

Mark Joey Tang has figured out a neat way to create geometry using position, depth or deep data.

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!
