auto pinning nuke cornerPin

 This little code place the cornerPin nodes 4 pin's automatically based on the bbox. If your image dosen't have bbox add a crop node and crop it as per your need.

Export Nuke's retime information

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...

Working with UV pass inside NUKE

Working with UV pass inside NUKE UV pass will allow you to re-texture surfaces and add some elements ( like text, batches, picture frame ) later in the compositing stage. Here i place my name on the surface and apply motion blur inside nuke. Creating UV pass inside MAYA: Maya 2012 have inbuilt UV render pass. Open up render settings under Passes tab select create render passes and choose UVpass and add. Maya->Render Settings->Passes->UVpass If you want to create custom UV pass Follow below link. http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=13481445&linkID=9242258 Enable float values for rendering For render UV pass from MAYA you must change your colour bit depth from the standard RGBA 4x8Bits per channel to RGBA (Float) 4x32 Bit (full float). Open up your 'Render Settings' and at the bottom of the 'Quality' tab change the 'Date Type' to 'RGBA (Float) 4x32 Bit. choosing File format f...

DeepEdgeSmoother

DeepEdgeSmoother Deep compositing became day to day work in many compositing studios around the world. Nuke having couple of Deep nodes to do Deep compositings. But Nuke still lagging Deep edge manipulating  nodes like edgeBlur, erode etc. I have faced many issues with blending edges while merging Deep inputs with 2D plates. Edge looks too sharp in many cases even there is Deep holdout.  DeepEdgeSmoother is applying softness on both end of Deep layer (Deep front and Deep back). Before: After: This gizmo add smoothness on both end of deep data to blend the edges more naturally. I hope this will help you guys. Download here: DeepEdgeSmoother
