pxTools – the complete package for Nuke

Hello people of the vfx world!

We know of all of the blogs that have different gizmos, all of the artists the give their python out, and the tutorials that are out there. Sadly, these things are never connected the way we want them in the world of production and learning.

In comes pxTools.
What is pxTools? It is a single community-driven toolset that standardizes plugins, and not in the give-us-your-money way.

The main aim of pxTools is to support itself. When you use a gizmo, and theres a bug, theres a place to report it. When you need help with said gizmo, theres a button linking you to a video tutorial. When you watch said tutorial, its presented in a standardized way.

A full release of pxTools will come out twice a year. Why? Because a tool in pxTools may be good, but somebody may come along and make version that is GREAT. This introduces a propellant to keep pxTools alive: competition.

Contributors to the pxTools project will have individual artist pages and the ability to have direct donations per tool. So when your tool is released in pxTools, you have direct exposure to the industry professionals using the tools.

There are already a lot of artists involved and lots and lots of neat tools and tomfoolery ready to be released. Panels, sample scripts, gizmos, python, tutorials and all sorts of things will be released with each new version. (Grooveshark, nukeChat, lots of other neat things as well.)

Whats left? You!

update value evey frame

I am not quite sure what I am actually after … so I am having difficulties to to look/find anything. Maybe if I try explaining someone can give me a hint 🙂

I want to run a python script on every frame. Or feed it with some value on every frame. Updating the values live … or something like that.

For example when I hit play I want the size of a blur to be 1 on frame 1. Then on frame 2 the blur is 2. So the blur size equals the current frame.

As an expression this would be simple, but I don’t know how to do this in python.

If I do:
num = nuke.frame()
nuke.toNode(‘Blur1’).knob(‘size’).setValue(num)

Nuke then sets the size to the frame that I launch the script and keeps that value. How do I get it to update the value for every frame?

Any help appreciated
Cheers

Learning Nuke and Keying in Nuke, any tips on this shot

Hi Everyone,

I am trying to get into Nuke more, as I used After Effects for most of my Keying and Roto and have taken classes on nuke from fxphd but trying to do some work on my own stuff as I go through the classes.

i am going throw the keying class in the First nuke class but cant seem to get a nice key for this shot. I know I could just use roto but I wanna see if I can key it first.

The main probably is the edges are very rough when I key, just looking for some suggestions on ways to tackle this in Nuke, Still getting used to the Node based layout .

change hue + sat on tracked green marker

Looking for help on the best way to tweak the colour of a green tracking marker. I’m using a tracker with the data linked via an expression to a paint/roto node which is isolating an area within a piece of footage of a green tracking marker which is then being removed by a MakerRemoval node. It’s doing an okay job, but I have a bit of green halo that I want to just remove the saturation and potentially hue as well to something more skin tone. I’m pretty new to nuke so not sure the best way to approach this. Cheers,

question about Furnace’s Wire Removal tool

Hi,guys.I selodom use wire removal tool of furnace in Nuke.Cause the computer may be slow when rendering if I use several wireremoval node in one script.
for example, a shot with many lines to removed.let’s say 8 lines.That means 8 wireremoval node in the script? Could I remove several lines in one wireremoval node?I didn’t find the way…..If I use 8 wireremoval node in a script,that’s a nightmare !(Rendering may last several hours….)
I know there’s other ways to remove wires in video,but learning more about furnace may do help one day.

Card to camera alignment question

I have a quick question that I hope there is a simple answer to 🙂

I’ve imported a camera from my 3D application, and I have a frame that I want to use as a reference for some matte-painting. For that I would like to align a card to that specific frame, so that it fills the view and is aligned to the camera. Is there a quick way to align a card to the current camera view?

I tried searching the Nuke PDF, but couldn’t find anything. I hope someone here can help!

CurveTool set frame range & execute

I want to create a script that executes nukes CurveTool. I want to set the frame range and render straight away.

cur1 = nuke.toNode(‘CurveTool1)
cur1.knob(‘go’).execute()

So far I get the "frames to execute" dialog box to open, but I dont know how to set the frame range via the script.

Please help me out
