With this integration, Houdini can read Substances in the form of .sbsar files, and Houdini users can tap into the power of procedural textures created with Substance Designer. Using the plugin is simple: after installing it, instance the Substance shader in a SHOP network.

It is now possible to load a Substance with all parameters exposed in Substance Designer.

It is also possible to reload the file if the .sbsar has been modified.

The Substance shader communicates directly with the Principled Shader, and the Mantra Surface shader is available on an experimental basis. In the same way, it is possible to describe the interfacing with any other shader via a description file. You can set the shader choice in the plugin options.

Next, add a material node in a SOP network and point to the Substance shader. The result is directly visible in the 3D viewport.
