Simugraph Viewer 2.0

Description

This script allows you to visualize a Cooked Simugraph using a .copy file exported from a Simugraph asset.

before using this tool make sure to download Graphviz

What you can see:

Connection beteween each nodes and each pins
Names of all nodes in the original simugraph
Type of nodes

Simugraph systems that are otherwise difficult to interpret once cooked, It is especially useful for analyzing overall architecture, understanding node relationships, and studying how different components interact within a system.
This tool is therefore intended for beginners, to help learn and better understand DTG methods, especially when dealing with complex cooked assets.

Exemple of simugraph done by the tool:

Warning

Important Note: This is NOT a Simugraph Decooker!
Why isn’t it?
Simply copying each node will not produce the same result: some parts require additional parameters and custom logic to function correctly.
I am not responsible for any issues or failures resulting from its use.
With this tool, you cannot see values, curve, or the connections of value expression nodes and value converters.
(Connections cannot be displayed for signal converter nodes.)
And its an image, not a .uasset, its not displayed in the editor as a new simugraph blueprint

Graphviz

Source Code Source code packages for the latest stable and development versions of Graphviz are available, along with instructions for anonymous access to the sources using Git.
Executable Packages Packages marked with an asterisk(*) are provided by outside parties. We list them for convenience, but disclaim responsibility for the contents of these packages.
Linux Precompiled binaries are available attached to releases on Gitlab, https://gitlab.com/graphviz/graphviz/-/releases. You may also find it useful to try one of the following third-party sites.

Installation Instructions

Installation:

Install the Graphviz (dot) library here: https://graphviz.org/download/
Add Graphviz to PATH.

First, go in the editor, search your simugraph, hit right click -> asset action -> export. Save it in the somewhere (in the same folder of this mod will be better)

Then Start the Simugraph Viewer, click on Browse, hit Analyze and thats it ! (the image will automaticly open and it will be save in /output)

Additional Comments

**Note: ** After extracting the .rar, keep all the folder and files in the same directory, dont mix them.
