When creating a material with a lot of parameters, you might want to create shortcuts to certain states of your material. Learn more about how to expose parameters in Substance 3D Designer here. This allows to modify the material quickly in the end application, and to have a lot of different looks and uses for one asset. Once exposed, this will allow the user to modify those elements directly in the application where they will be used, such as Substance Painter, UE4 or C4D. When you create a material using Substance 3D Designer, you can choose to expose parameters, such as the amount of an element, a color etc. Image: "Rock Substance 003" by Lennart Demes ( link) This means that you can dramatically reduce the amount of space dedicated to textures in your project.
I f you create a Substance material that is 100% procedural, the file will be extremely light. You will be able to make changes to your material until the last minute, without having to redo the texture from scratch. Not only will you get the generated textures, but all the exposed parameters remain available, and modifiable. A layer of procedural details can be added on top of the scans, or several scans can be merged to create a completely new material.Ī Substance material can be published, then used in any external application that handles the Substance Engine (such as Unity or UE4 ). The materials can be 100% procedural and created in Substance 3D Designer, or be created via a scan or a picture. Your talent and your imagination are the only limits to what you can do. It means that the author of the Substance material can decide to expose parameters in order to give control to the final user.įor example, it's possible to change the amount of dust on an object, or the color of a soccer team jersey. A Substance material is a parametric material and not a static, “dead” texture.
