Through the years I crafted a large number of Nuke gizmos to improve bits of compositing in Nuke while learning about image manipulation.
All were adapted as much as possible to Nuke standards to make them simple and intuitive to use, and they are currently used extensively by Nuke compositors. I try to keep them updated to the latest Nuke versions and actively look for feedback on how to improve these tools.
Some features of my nuke gizmos:
aPMatte v2.0 is a Blinkscript-based Nuke gizmo that lets you generate mattes and 4D noise based on a Point Position pass.
v2 includes new shapes and modes, a 3D-space view of the matte and point cloud, and accepts an Axis or Camera input. Also, lets you preview the p-matte over an image input and merge the alpha with the incoming one through different operations.
apDespill v2.0 is a blinkscript despiller and chroma keyer capable of picking a specific tone and with image-based input options for most of the controls. v2.0 lets you choose between a despilling and keying algorithm, bringing new options such as turning the despill into a color or using it as an iKeylight.
If you just want a basic despill, its default values should already be enough and the tool will avoid any extra calculations.
apChroma is an advanced chromatic aberration and drift gizmo, that works through a sub-frame blend of different values on an STMap and Transform, while creating a user-defined color spectrum.
apChroma can calculate a multi-channel alpha for correct merging of the result onto a plate, and the included apChromaMerge node will perform the multi-alpha merge operation.
ColorSampler is a tool that outputs the average color of a target input (or the src image if there’s no target input), weighted through the area input or the whole frame. It can also calculate the maximum or minimum value over the area or whole image. Additionally, you can directly remove color flickering, or apply it from a second image.
You can think of ColorSampler as a live version of CurveTool with some additional features using the power of Blinkscript, where instead of being limited to a rectangle you can plug a roto to use for the sampling area… or a key…
apGlow is a lightweight exponential glow effect with advanced control over the steps, falloff, distribution, color and other useful parameters.
Tip: If you use the default settings and only change the size and falloff controls, this tool is an exponential blur, useful for diffusion effects (eg. before merging an atmos element).
Multiply the rgb or rgba colors by an arbitrary 4×4 Matrix. Useful for transforming vector passes like Position or Normals. You can also plug in an Axis or Camera node into the axis input, to apply its transformations.
C44Kernel is a simpler, Blinkscript-based alternative to the C44Matrix node by Ivan Busquets, which is incredibly useful but has the compatibility limitations of a plugin.
apEdgePush is a vector distort edge warp that distorts the edge colors outwards to get rid of visible fringe. By default looks for alpha in the img input but you can plug in a custom matte to the matte input. Switch channels to rgb and warp before the Premult in order to warp the image “within” the premultiplied alpha region.
Tips: Prioritize using apEdgePush on edges that have a thin visible fringe. Use multiple apEdgePush nodes with lowered opacity to produce a filtered result with no visible distortion.
apDirLight, one of my first published tools, lets you simulate a simple directional light through a Normals pass, by picking a color from such pass and then tweaking the radius, falloff and hardness of the generated mask.
It also proves really useful as a hue keyer, and I actually use it more for this purpose in production. Simply pick a color from the image and look at the alpha.
Most of my nuke gizmos are part of Nuke Survival Toolkit, a free and portable tool menu for the Foundry’s Nuke featuring a hand-picked selection of gizmos collected from all over the web, organized into 1 easy to install toolbar.
Nuke Survival Toolkit was created by my friend Tony Lyons and features many awesome tools from the community. It is currently used by studios and freelance artists everywhere.
