MatSynth: A Modern PBR Materials Dataset

Giuseppe Vecchio, Valentin Deschaintre

Abstract: We introduce MatSynth, a dataset of 4, 000+ CCO ultra-high resolution PBR materials. Materials are crucial components of virtual relightable assets, defining the interaction of light at the surface of geometries. Given their importance, significant research effort was dedicated to their representation, creation, and acquisition. However, in the past 6 years, most research in material acquisition or gen-eration relied either on the same unique dataset, or on company-owned huge library of procedural materials. With this dataset, we propose a significantly larger, more di-verse, and higher resolution set of materials than previously publicly available. We carefully discuss the data collection process and demonstrate the benefits of this dataset for material acquisition and generation applications. The complete data further contains metadata with each mate-rial's origin, license, category, tags, creation method, and, when available, descriptions and physical size, as well as 3M+ renderings of the augmented materials, in lK, under various environment lightings. The MatSynth dataset is released through the project page at: https://www.gvecchio.com/matsynth.
