A high-resolution texture file for designers to use in interior design renders and to integrate real-world natural stone for the metaverse interior and exterior design. Kuroca is a black quartzite from Angola owned by Nikolaus Bagnara S.p.A., a family-owned business from Appiano Italy who started their company way back in 1948. The file is a high-resolution photo of a real quartzite slab of this natural stone, so it is unique and has a one-of it`s kind vein pattern. Each render is an example of how the file could be used and contains the original high-resolution image. We are using this collection to test the interest of the designer community for such unique digital copies of real-world material products. This slab was already sold and will be used for a kitchen top or other decorative elements in someone's home. If successful, we will help the stone owner to promote more beautiful material from their quarries with the possibility of shipping the physical version of the stone slab to the NFT buyers for additional payment.
