About us
Where Artistic Precision Meets Technical Mastery
AION SIGNA was founded on the idea of uniting two disciplines rarely found in one practice: a refined artistic eye and production-grade technical precision. Oleg’s expertise — 20 years in 3D visualization, grounded in classical artistic training — holds both threads together and sets the standard behind every model the company creates.
We see ourselves as visionaries of what digital visualization can become once it takes physical form: not simply a solution, but one that is as close to art as it is to flawless technical execution.
Every AION SIGNA piece carries that discipline: an artist’s judgment of proportion, expression, and character, delivered with the rigor of a professional production pipeline. The result is not a technical reconstruction — it is a likeness that stands as a work of art.
That is the standard behind every likeness AION SIGNA creates — for the families who trust us with a memory, and the manufacturers who trust us with a design.
About Founder
Oleg Koreyba — Co-founder & Lead Digital Sculptor
Trained as a painter. Oleg was born in Ukraine and trained classically in drawing, painting, and anatomy. By his early twenties he had painted monumental frescoes, responsible for every face and hand in a church spanning hundreds of square meters. That grounding in anatomy, proportion, and expression remains the foundation of everything he sculpts.
Two decades in digital production. He moved into 3D and spent more than 20 years in digital sculpting and character art for AAA games, VR, hologram, fashion, and cinematic productions. The work covers facial likeness, anatomy, hands, eyes, clothing, photogrammetry, and production optimization: getting a face right, and making it hold up in a real production pipeline.
Selected projects include Metro Exodus and its DLCs, Metro 2033, Metro 2039, ARKTIKA.1, Ritual Tides, CrimeCraft, and You Are Empty.
Collaborations. Working directly with Bandai Namco, Smilegate, 4A Games, AXYZ Design, and Vertpaint Studios, and, through production partners, contributing to titles from Microsoft Games, Ubisoft, Activision, Nintendo, THQ, and Deep Silver.
Likeness at its most demanding. His portfolio includes digital likenesses of internationally recognized public figures, built entirely by hand from a few reference photographs, without scan data. Among them is a full-color hologram portrait commissioned from the UAE that is now held by a national government. He has also delivered a completed bronze monument for a private client in the United States.
Back to the canvas. In 2024 Oleg returned to painting. His work is held in private collections across the USA, UK, Ukraine, Malta, Spain, the UAE, Japan, Israel, and China.
