Version 2020.2 (2.2)

Substance Alchemist 2020.2 "Udon" introduces a new AI Powered Image to Material process to transform a single image input into a fully PBR Material, an improved Material Creation Template, lot of workflow and usability improvements and new content such as new filters.Release date: June 15, 2020

Major features

Image to Material (AI Powered)

The Image to Material template has a new setting named AI Powered. This new setting provides better results to generate a high quality PBR material from a single input image.

The AI Powered setting uses machine learning to recognize shapes and objects and accurately generate height and normal information. This setting also includes the delighter filter to remove any shadows and highlights. This new setting works best with outdoor materials, as the algorithm was trained with grounds, pebbles, bark, stones, and other exterior based surfaces lit with natural lighting. Further updates will bring more flexibility and versatility of supported materials. For more details see the dedicated documentation page.

Here is a comparison of the height information generated by the two algorithms with their default values:

The AI Powered setting requires specific hardware. It is only available on Windows and Linux with an Nvidia GPU. See the technical requirements for more information.
