Important note to Blender users:
If you previously installed the nxt_blender addon please remove it from your addons folder. This only applies if you installed version 0.1.0 of the blender addon.
- If you used the install script also delete the nxt folder from your user addons/modules folder.
- If you used pip to install nxt into Blender's python please run the following pip uninstall nxt-editor nxt-core.
Once you've uninstall the old version follow the README instructions in the nxt_blender.zip.
Additions:
`+` Initial setup for nxt_unreal plugin.
`+` One click Blender context.
`+` Support for contexts that aren't strictly Python interpreters.
`+` Code editor now displays a "Double Click To Edit" message. Fixes 133
`+` Added collapse/un-collapse animations.
`+` Node LODs
`+` Added user prefs for `fps`, `lod`, and `animation` all on by default. In your user prefs you can toggle these using the keys previously stated; for `lod` it must be an int or float value, `0` to disable, default is `0.4`. Must restart editor for changes to these prefs to take effect.
Changes:
`*` Centralized blender integration functions into a single class that can be called without the addon being loaded.
`*` `launch_editor` now has a kwarg to NOT call `app.exec_()`, needed for host DCCs that aren't themselves a QApp.
`*` Bug fix: When changing focus to and from NXT it was possible to get into a state where zooming became impossible.
`*` Hookup closing signals and update both packages
`*` Bug fix: Fixed bug that caused the invalid runtime node dialog to spawn every time a snippet was run. Fixes 155
`*` Bug fix: When a workflow button executed its descendants, nodes under a disabled descendant would still execute. This was considered unexpected as it did not follow the "normal" execute order rules.
`*` fix unreal plugin build paths
`*` Bug fix: Code editor wasn't displaying the data state in the top right like it used to.
`*` Bug fix: QSignal traffic jams could cause the workflow tools to throw exceptions.
`*` Bug fix: Clearing breakpoints would emit node's changed twice.
`*` Improved visibility of collapse arrows.
`*` Bug fix: Collapsed nodes from the same layer as ancestor parent wouldn't generate a collapse arrow.
`*` Bug fix: Sometimes an exception about non-iterable object types would be raised When updating the workflow tools window.
`*` Bug fix: Corrected folder paths for Blender.
`*` Blender's `Update NXT` button (not the update dependencies button) will now update the addon file as well as the backend.
`*` Minor drawing optimizations
`*` Update make maya plugin graph to run correctly in python 2 or 3
Removals:
`-` Removed Blender installer script as its functionality has been moved to the `nxt_blender.py` addon.
Notes:
`...` Switched to using `subprocess` as the pip approach.
`...` FPS counter added to the bottom left of the stage view. (Low numbers aren't bad if you're idle)

News: Studio rigging and pipeline tool released as open source
8 January 2021
[nxt-dev.github.io](https://nxt-dev.github.io/)
(images below)
Released today, NXT (Node eXecution Tree) is a new open source python layering and sequential execution tool for animation and VFX.
NXT enables visualization of complex scripts and easy cross-department collaboration. It’s code with layers with a nice way to see and change data. “Our vision for NXT is to simplify production workflows and provide a visual bridge between artists and developers,” says show supervisor Aaron Adams. “With this release, we hope that studios worldwide can take advantage of this visual way to manage data and processes in the pipeline.”
NXT is the first part of an ongoing initiative at Sunrise Productions to release its tools as open source. “Sunrise has benefitted so much from open source projects, and we want to engage with and support the global animation community with our tools,” shares Tim Keller, CTO of Sunrise.
The primary function of NXT is to visualize and automate programming tasks related to computer graphics and linear processing. The intent is to bridge the gap between one-off scripting and general-purpose tools through the use of inheritance, layering, and string tokens.
“NXT has allowed us to get a large number of character rigs up and running in record time with layered NXT templates. It has also allowed us to tightly integrate our workflow tools right into NXT,” says Matt Schiller, rigging supervisor.
Sue Sauer, USD pipeline TD, shares the following: “NXT's visual code style and ability to layer and instance graphs suits USD very well. In my opinion NXT adds a needed level of management to USD that makes it more ‘user friendly’ without the TD having to subscribe to any particular DCC's workflow.”
**What does NXT do?**
In the simplest of terms, NXT combines multiple layers of nodes into a single composite layer that is then executable. It is something like Photoshop layers for code. Users are able to mute, solo, override, and extend layers of code. The resulting composite clearly visualizes where attributes and values originated. Colors, node paths, and conveniently placed links allow users to quickly debug code.
**Why use NXT?**
The core functionality of NXT was built with insights from industry veterans with both technical and artistic backgrounds.
The key principles include:
- Visualize and map what a complex script is actually doing. NXT uses existing conventions of nodes and connections, but it goes further and adds string tokens to instantly visualize attribute values. Tokens can be used almost anywhere inside NXT and are dynamically resolved during execution. The user sees exactly what data is flowing around without an external debugger.
- Encourage collaboration through layering and multi-context/application graphs. With NXT’s layering system, it is easy for departments to share base graphs. Graphs are layered non-destructively, preserving the base layer. With multi-context graphs, a Maya user can directly call a Houdini graph from inside Maya. Alternatively, graphs can call other graphs in the same context, allowing interdependent graphs to be developed simultaneously.
- Make code accessible to everyone. Artists can modify attributes and learn to make simple code changes that would normally require a TD. NXT is not visual programming, but rather a friendly visual portal into code, specifically tuned for animation workflows.
**Background**
NXT began as a research project led by former Disney simulation supervisor Aaron Adams while an artist-in-residence at the School of Visual Art and Design at Southern Adventist University. Adams shepherded work on NXT with the original development team while serving as show supervisor at Sunrise Productions. NXT became the foundation for the feature animation rigging pipeline and USD integration at Sunrise.

Emphasis is placed on developing talent for the purpose of benefiting others through service. Character animation students are encouraged to tell narrative stories that reflect truths and concepts that focus on external means of change. Under the guidance of Disney veteran Hendel Butoy, instruction is focused on collaborative production where a studio-like environment is established during the third and fourth years of study. Southern Adventist University is a graduate and undergraduate co-educational university with more than 3,100 students. The university offers graduate degrees, baccalaureate degrees, and associate degrees on its 1,000-acre campus in Collegedale, Tennessee.
