Substance 3D Sampler
Substance 3D Sampler allows you to create and iterate on material collections by tweaking and mixing existing materials, or by extracting new materials from scans (single or multiple images).
A new set of powerful tools combining different technologies and creation methods (procedural-based, capture-based, AI-based and manual) will help you manage entire material libraries, and export them to other applications.
If you are looking for the documentation of the legacy version Substance Alchemist, it can be downloaded as a PDF file here. This documentation now focuses on Substance 3D Sampler.
