This page is the landing page of documentation regarding authoring Substance model graphs to create parametric 3D models in Substance 3D Designer.

A Substance model is a parametric 3D model which is procedurally generated and can be dynamically modified in real time. Its shape and mesh are constructed on-the-fly using a set of instructions which are implemented by the user, by adding and connecting nodes in a Substance model graph.

The general workflow for authoring Substance models is as follows:

To get started, take a look at the Working with Substance model graphs page and go through the other pages in this section in order for a smooth learning path.

Then, pick up a Sample graph and play around to get a sense of the powerful nodes at your disposal!

'What does this node do', you ask? The Nodes reference for Substance model graphs section is there to help with the entire catalogue of available nodes, rich with descriptions of all their parameters.
