Nuke Tutorials and Tools

Some cool and very help full nuke short-cut's Here i'm going to share some cool and very help full nuke short-cut's with you friends. These are all my favourite short-cut's inside nuke. 1. "ctrl+up arrow or ctrl+down arrow" you can move your selected node to above or below the next node. But this will not work with multiple nodes. You cant move multiple nodes with this short-cut. (you can create some python code for doing this) 2. "crtl+shift+c" This will pop-up the selected nodes "tile_color" picker window. You can color code the selected node or nodes same time. 3. "ctrl+right arrow & left arro w" This will jump into half of the time in your time line. example: If your current frame is 50 ctrl+left arrow will jump to 25th frame. If you give it again it will jumb into 13. Your mouse should in viewer window. This short-cut also work with key frames. you can jump in-between the...

Nuke particle system After some request's i'm creating this post for various nuke particle example. 1. Bouncing balls using Nuke's particle system. Here i  created simple bouncing balls scene using nuke's particle systems. I used some "trick" to create shadows and hiding the objects while rendering using some shader trick.  Example video: This is the node graph of this nuke script. Hope this will help you guys.  More particle tut's in future...... Script:  Nuke_Particles_v04.nk

autoPivot.py Transforming, rotating, skewing and scaling all are happening based on the pivot point in every image editing software. So placing the pivot point in right place will handy to do above things. In nuke... transform node's pivot point set to centre based on the project format by default. If our image is in a part of the format. While doing translate, rotate and scaling this causing some problem. To do uniform scale or rotate we will move the pivot to image centre or image bottom centre by holding " ctrl+mouse click ". But we cant place it exactly in the middle or bottom middle. How to reduce this manual job ? Auto pivot.py will help you to place the pivot to centre of the image or bottom centre of the image by using short-cut keys. Pivot centre after run the script: Pivot bottom centre after run the script: Auto pivot needs "bbox" to perform this action. So keep your bbox set to the image size. This little python script sa...

Export Nuke's retime information To 3D packages: This is happen while working with production. In most cases retiming is done beforehand or at the end of a comp. Some time shots getting retimed after Match-move is done. By that time Nuke's retime data (curve) will help to match the tracked camera to new retimed plate. Here is the trick to export nuke's retime date (curve) to 3D packages such as maya, max, Houdini etc. Here im explaining how to export nuke's retime curve to maya. Constant re-speed. I want to retime my input by 200%. Add a retime node and change the speed to 2. Don't forget to change the filter option to None . Retime node doesn't generate retime curve at all. So note down the output range. It changed from original range 1001 - 1042 to 1001 - 1021. Which means our input ended with 1021. Add a TimeWarp node and set keyFrames based on our retime output result. Set a key frame at 1001 as 1001 in input frame knob. Got...

flopFlip.py Nuke doesn't have this small and very handy utility built-in. For doing this function in nuke we need to use "VIEWER_INPUT" method (or) add mirror node and connect it with a (any) node, then constantly check and un-check the Horizontal or vertical knob. Finally you have to delete the mirror node. flopFlip script dosen't need above step 's. Just press ctrl+F for flop, ctrl+shift+F for flip. Before:  After: flopFlip will help you to flop & flip your current viewer result. I use to do this for checking my final comps and review my shots. Playback software's like RV, frame-cycler and other tools have this handy function. flopFlip: Hope this will help you friends. download: flopFlip.py nukepedia:  nukepedia ''' Created on 21-apr-2013 @author: satheesh-R mail - satheesrev@gmail.com http://satheeshnuketutorials.blogspot.in/ Add following lines to your menu.py: import flopflip menuBar.addComman...
