In 2025 i had the fantastic opportunity to create my own Substance Source Signature Collection in collaboration with the Adobe Substance 3D team.
My collection is a series of 10 fully parametric substance files that cover celestial objects and surfaces - from big objects like stars to closeups of the inside of a meteorite. To learn more about the project please read the accompanying article on Behance:

The cratered moon was inspired by Earth's moon and the planet Mercury. The ice moon was inspired by the Jupiter moon Europa. Both substances are fully parametric and allow the creation of a wide range of different looking surfaces.
