a 3D Roto Tool for Nuke
MaskMe it’s a Nuke Gizmo that I’ve been developing while working at “The Senate VFX”. As a Compositor, quite often we end up doing a repetitive task and in my case as a 3D oriented dude, Camera projection is one of the operations that I use on an hourly base. 90% of the times, when working on a shot I end up using or creating a camera to facilitate all the common task such as roto/painting/patching etc..
What does it do?
Simplify the roto of non-organic objects, 3D stabilising and reversing the stabilization in one go.
When should you use it?
Every time you have a camera or you will have to matchmove a shot. Instead of spending time moving roto shapes around you can easily do the same operations with a few keyframes in a much more precise way.
Where is the magic?
There is no magic! it’s a common technique, often avoided because you will need at least 10 nodes to make it work, re-create the setup multiple times and make sure that everything is the right place/order. What I’ve done is just refining the operations inside making everything simpler and user-friendly.
How does it work? easy 🙂
- Plug the undistorted plate
- Plug the camera
- Position a card or a cube in right XYZ coordinate – Locators, Proxy Geo, Lidar data or a PointCloud ( Built-in in MaskMe ) are your friends here
- Set Reference Frame – Choose the frame where most of the details of the area/object you are trying to mask are visible.
- Switch to the Roto viewer and roto what you see! Internally MaskMe is stabilizing the undistorted plate based on the card/cube position. This will allow you to be very precise and very, very, fast!!!
- Switch to the Render viewer. Job Done!
This is what is happening behind the curtains:
- Fixed Unplugged Output when re-opening Nuke Script
- Fixed bug that will not allow you to plug anything after the gizmo until you look at it first.
- Removed Point Cloud Generator from the gizmo
- Fixed Expression Link showing in the nodegraph when using more than one gizmo.
- Fixed black screen bug due to bad switch looking for non-existing knob
- Download and copy the folder Ivan_Sorgente_Tools in your .nuke directory
- add to the init.py
- add to the menu.py
istools = toolbar.addMenu(“IvanSorgente”, icon=”ISToolsLogo.png”)
istools.addCommand(“MaskMe”, “nuke.createNode(\”MaskMe\”)”, icon=”MaskMeLogo.png”)
