Adobe Substance 3D Modeler is a 3D modeling software developed by Adobe. It is a part of the Adobe Substance 3D suite, which includes other applications such as Substance 3D Painter and Substance 3D Designer. 


With Substance 3D Modeler, users can create 3D models using a variety of tools such as polygonal modeling, sculpting, and parametric modeling. The software also includes a library of pre-built 3D assets that can be used as a starting point for creating more complex models.


One of the unique features of Substance 3D Modeler is its ability to work with parametric modeling. This means that users can create models using mathematical equations and algorithms, which can be adjusted and modified in real-time. This allows for greater flexibility and control when creating complex models.


Substance 3D Modeler also includes a range of tools for texturing and materials, which can be applied to models using a node-based system. This allows for the creation of highly detailed and realistic materials, such as metal, wood, and plastic.


Overall, Adobe Substance 3D Modeler is a powerful and versatile 3D modeling software that is suitable for a wide range of industries, including gaming, architecture, and product design.
