[p]This update brings a redesigned graph creation window (with direct access to samples), enhanced noise nodes for more creative control, and an improved node menu for an easier navigation. For further details, see the complete release notes.[/p][p][/p][p]Release date: December 11th, 2025[/p][p][/p]

Improve graph creation

[p][/p][p]In this release, the graph creation window has been comprehensively redesigned to enhance the initial user experience in Substance 3D Designer. The primary goal of this update is to streamline the template selection process, allowing users to efficiently identify the most suitable template for their requirements.[/p][p align="justify"]Thumbnails offer instant visual references for the intended material types, while detailed tooltips supply all pertinent information. For improved organization, templates are now classified into specific categories such as materials, filters, and scan processing.[/p][p align="justify"]Although the main interface has been upgraded, users continue to have access to previous views, including list, packages, and directories options.[/p][p][/p]

Embedded samples

[p align="justify"]With the launch of our redesigned graph creation window, we've added a variety of sample materials directly inside the software. This enhancement is in response to your request for better access to learning resources.[/p][p]To meet this need we have included material samples such as fabrics (including leather and satin), wood, metal, plastic, ceramic and more. These examples are intended to help you start your projects with ease and get acquainted with the main family nodes available in Substance 3D Designer[/p][p align="justify"]Each graph is annotated, carefully organized, and contains a minimal number of nodes to make it as easy to understand as possible.[/p][p align="justify"]You can access the samples in the 'Material samples' category when creating a new Substance graph, or directly from the Home screen using the convenient 'Go to samples' button.[/p][p align="justify"]Alongside these foundational materials, we've also provided advanced samples to demonstrate how to use FX-map and Pixel processor features more effectively.[/p][p][/p]

New noises

[p]Noises play a crucial role in the majority of graphs, which is why we have focused on several key enhancements in this release to improve their functionality and usability.[/p][p align="justify"]With this update, we have introduced better support for non-tiling scenarios, ensuring that noise patterns behave as expected without mandatory tiling. Previously, noise nodes were either forced to tile or produced incorrect results when tiling was disabled.[/p][p align="justify"]Most noises now include new parameters, providing users with greater creative control. These additional options empower graph authors to fine-tune the appearance and behavior of noise within their workflows.[/p][p align="justify"]Finally, bitdepth is no longer hard-locked to 16-bits. You can now override the bitdepth setting on individual node instances, allowing you to achieve higher detail and dynamic range when needed, or optimize your graphs for performance.[/p][p align="justify"]Examples:   Cells 1   Clouds 2   Directional scratches   Moisture noise 1[/p][p][/p]

Hierarchy in node menu

[p]To address the challenge of locating specific nodes within the extensive library, we have introduced categories in the Node menu.[/p][p align="justify"]The vast number of available nodes can make it difficult to quickly find the desired one. To streamline this process, a new Group attribute has been implemented at the graph level. When this attribute is defined, it is used to organize and sort the search results.[/p][p][/p]

Default output

[p]When a node has multiple outputs, it is not possible to display all of them simultaneously in the 2D view or as the node thumbnail. The prevailing guideline in such scenarios is to utilize the first connected pin, or, if none are connected, the first output by default.[/p][p align="justify"]However, this approach may not always yield optimal results. For instance, in some Spline nodes the first connected pin often represents spline coordinates data, which is not suitable for previewing purposes.[/p][p align="justify"]To address this, a default output attribute has been introduced. This feature allows the graph author to specify which output should be displayed by default, thereby enhancing the intuitiveness of node usage and facilitating a clearer understanding of the authored graph.[/p][p align="justify"]Play with the image below to see the difference before and after the default output definition. [/p][p][/p]

'Is defined' node

[p]When working with function graphs, you may need to determine whether a variable exists within the graph.[/p][p align="justify"]For instance, detecting the absence of a variable enables you to provide a fallback value, ensuring the function behaves as expected without requiring every input to be explicitly set. That’s why we added the 'Is defined' node.[/p][p][/p][p][/p]
