Well, I did work on my scripting skills and I really want to share it.
This will be the start of a new series, that will be updated as often as I find time. All the scripts and gizmos I will share are production tested and found useful.

Tut of the month: Nuke - Stereo3D inside Nuke

Hi,it has been a while since my last tutorial. I’m really busy at the moment but I couldn’t resist on testing the new stereo3D abilities in Nuke. And I was so impressed by the result, that I desided to write a short tutorial on how to create your own stereoscopic scene inside Nuke5. Take a look on the final result below, using the anaglyph technology to view it with Red-Cyan glasses.

As you can probably see, the scene is from a Tutorial DVD sold by the Gnomon School. It was usually made for a camera projection tutorial in Maya. What I’ve done now is, I recreated the whole scene inside Nuke, using 3d geometrie. I then projected the textures, using a camera inside Nuke. To go more into detail read on here

Tutorials of the month: Nuke Customization

It is time to post a new tutorial, and this time I want to give you some tips on doing customization for a better workflow. As you probably know, Nuke is based on the programming language TCL, and with the help of some scripting knowledge you can easily set up some hotkeys or preferences. Now let’s start:
The first thing I will explain is the way how you set up your own plugins folder. When you have installed Nuke, you will find a folder called plugins where a file called init.tcl is stored. Open this file in a texteditor and add the following command:
plugin_addpath “/Users/myname/nuke_plugins”

myname should be replaced with your username of course! and if you are on a windows system, then add the drive letter also, but be sure to use / and no backspace !! Now create the folder called nuke_plugins in the right place, and then create a new menu.tcl file in your text editor and store it inside your nuke_plugins folder. You have now told Nuke to look into your “nuke_plugins” folder everytime it is run, and you can simply place every plugin or gizmo inside your selfmade folder and access it via your own menu.tcl.

Tut of the month: Nuke - Stabilize using the Reconcile 3D Node

I got really good feedback especially on the Reconcile3D Tutorial, so I decided to continue this with another tip of the month. This time I want to use matchmoving data to stabilize my footage. So for the 3d matchmove I usually use Pftrack, which is simple and really solid. You can use whatever software you like of course ;-)

So when the tracking is done I usually export my data to Maya (in the newer version of Pftrack, you can export a Nuke script as well) to check if everything matches.

Tutorials of the month: Handy Nuke Tricks

This month I decided to show you some tips and tricks that will help you working with Nuke. So let’s start with a question I got yesterday pointed on the creation of a ramp:

1. How can I make a 2 colored ramp ? The answer is easy but a little bit weird. Instead of using the Ramp node, that is located under the Draw menu, you simply use a Bezier. Draw a bezier mask around your image and jump to the color tap inside the Bezier node. There you see the ramp pulldown menu, and you would choose linear. Now you can select your colors and change your ramp in the viewer.

Tutorials of the month Nuke Reconcile 3D

So welcome to my first tutorial on Nuke. I hope I can continue this monthly, so that you will check this site regularly!
Why have I chosen Nuke and why the Reconcile 3D node for my first tutorial ?? Well this is pretty easy to explain. Nuke is my favorite compositing tool, first because of its speed and flexibility, and second because it rocks on my macbookpro! The reconcile 3D node was chosen, because it saved me so much time, that I spent in Shake tracking objects even though I had a 3d camera.
