Gizmos

Breakdownerizationer

A tool to automate the creation of simple breakdowns in Nuke. No bloated features, just does what it says on the tin.

Usage Notes:

  • Currently only supports pre-rendered layers.
  • Breakdown types include:
    • Wipe Left-to-Right
    • Dissolve
    • Slide Layer In, Top-to-Bottom

Cloudtastic

A light-weight, element-based atmospheric fog box scriptlet.

Usage Notes:

  • See "Usage:" notes on CLOUDTASTIC_CONTROLS NoOp (pictured below)
  • Expects atmospheric fog or cloud elements from your elements library.
  • Trades off having heavy animated particles for randomly scattered sprites, which are frameheld for speed.
  • ScanlineRender node outputs deep data so you can use in conjunction with deep renders, but please note:
    • If your camera flies through elements, they will pop on/off as the particles are just simple cards. Cloudtastic has a "kill area size" to prevent this, or you can use DeepCropSoft to fade them on/off as they move closer.
    • If you have a deep render that moves through Cloudtastic's space, you may also see popping as it travels through the particles. As Cloudtastic is a light-weight hack, the best way to deal with this is to use a normalized depth pass (0 - 1 range), and mult it into the output render of Cloudtastic. While not 100% accurate, is it usually close enough when you need a quick solution!
    • If you need more accuracy, buy your FX department a beer to render true, deep volumetrics! :)

DeepMerge_Advanced

Like the DeepMerge node, with an option to soften the blend point.

bm_CameraShake

A replacement for Nuke's default camera shake node. Offers more control over 3 different frequencies of camera shake, and also shakes the centre-point, giving more detail to sub-frame motionblur. Also has options for how to deal with edge-of-frame pixels, so pushing-in isn't always your best option anymore!

bm_CurveRemapper

Useful for remapping arbitrary animation curves, such as those from the CurveTool. Automatically detect an animation curve's min & max values, then remap them to new min & max values.

bm_EdgeMatte

A simple gizmo to create an edge-outline from an existing rotoshape/matte.
(there are plenty of newer gizmos like this one with different features. If you have a better one, please let me know!)

bm_OpticalLightwrap

Like bm_OpticalGlow, this adds exponentially-increasing blurs together to produce a more optically-correct, natural lightwrap.

bm_MatteCheck

A simple gizmo to help QC roto and keys, by overlaying a transparent colour, viewing a premultiplied image over grey or a checkerboard (for light and dark values).

bm_NoiseGen

Generates a random noise curve based on a minimum, maximum & frequency value.

bm_OpticalGlow

Adds exponentially-increasing blurs together to produce a more optically-correct, natural glow.




Python

bm_AutoContactSheet.py

Powers up Nuke's default contact sheet with features such as:

  • Automatically lays out your images to maximize screen coverage, with no gaps.
  • Automatically labels what each input is.
  • Automatically sets its own resolution, based off your Project Settings' format.
  • Adds a User knob for easy resolution scaling in case you want more detail, or more speed.
  • Adds a few controls to adjust our automated text nodes.

bm_DefaultBackdrop.py

Adds better backdrop node defaults & presets. ALT+B is the shortcut, or you can use the menu to grab a specific colour.

bm_CurveUtilities.py

Adds some handy animation shortcuts to a knob's right-click menu:

  • FrameHold animation.
  • Set this frame as reference frame.
  • Remap values between 0 and 1.

bm_EnableTrackerTRS.py

Adds a META+T hotkey to enable all T, R & S checkboxes in a selected Tracker node.

bm_JumpToKeyframe.py

Map Up and Down arrow keys to jump between next & previous keyframes.

bm_MultiIBK.py

Creates the usual IBK setup with 6 expression-linked IBKColour duplicates.

bm_NodeComment.py

Adds META+C shortcut to create a node's label, so you don't waste valuable clicks opening a node and switching to the Node label.

bm_NodeSandwich.py

Sandwiches selected node between two nodes (like an unpremult/premult, or lin2log/log2lin conversion).

  • CTRL+SHIFT+L creates a Log2Lin / Lin2Log sandwich.
  • CTRL+SHIFT+P creates an Unpremult / Premult sandwich.

bm_NukeColourConverter.py

Convert Nuke's hex colour to easier web-based hex, or RGB integer based off the colour sliders we're used to using in Nuke.

bm_OperationSwitcher.py

CTRL+ALT+S toggles a Merge node's operation between over/under, mask/stencil, plus/from, etc.

bm_PulldownKnobCycler.py

PGUP and PGDOWN cycles through operation and channels knobs on any selected node.

bm_QuickKeys.py

Adds an easy way to set on/off keyframes on mix knobs & switch nodes.

  • META+, sets the current frame "on", and the previous frame "off".
  • META+. sets the current frame "on", and the next frame "off".
  • CTRL+META+, sets the current frame "on", and both the next & previous frames "off".
  • CTRL+META+. sets the current frame "off", and both the next & previous frames "on".
  • META+/ opens a dialog box to manaully set a first frame, last frame, and a fade duration with values other than 0 or 1.

bm_ShuffleShortcuts.py

Creates shuffle node shortcuts for shuffling a single channel to all other channels.
Note: Currently uses the old Shuffle node...

bm_SmartMerge.py

Upgrades Nuke's default m hotkey to be context-aware:

  • If a set of 2D nodes & Deeps are selected, create DeepRecolor nodes.
    • If you have multiple sets of Reads & DeepReads selected, SmartMerge will hook the pairs up based on how similarly the filenames of the Reads & DeepReads are named.
  • If only Deep nodes are selected, create a DeepMerge node.
  • If a ScanlineRender node is selected, intelligently choose whether to Merge or DeepMerge depending on other nodes that are selected.
  • If only 3D nodes are selected, create a Scene node.
  • If only 2D nodes are selected, or if nothing is selected, create a vanilla Merge node as per usual.

bm_Smoothie.py

Easily smooth curves in Nuke's curve editor. Currently only supports single knobs (e.g. multiply that hasn't been split into RGBA knobs, mix knobs, etc.).
Click here to read a tutorial on how this was created, and how to programatically edit animation curves in Nuke.

bm_SwapInOut.py

Easily fix scripts that use in & out, instead of mask & stencil.
If you do this, Conrad Olson's video is required watching.

bm_ViewerToggle.py

Adds ALT+Q shortcut to toggle viewer exposure & gamma between custom value and default.

bm_netCopy.py

Share a selection of nodes with other users on the same network.
Say goodbye to copy/pasting lines of text via IM or Email!
