By taking advantage of the Substance Engine, changes to the Substance files can be made inside the converter. The results can be applied automatically to a Thea material which the user can preview under different settings. Physically-based materials designed with the Metallic/Roughness template are automatically converted to their equivalent in the Thea material system. Additionally, the user can create his/her own combinations although the result is not guaranteed to be physically accurate. Batch conversion of Metallic/Roughness Substance files to Thea materials or to a Thea material pack is also supported.
