The article is devoted to the description of the algorithm for obtaining a complete model from a colorless model of a stone and its prototype image with a material that allows you to manually make changes for greater detalization. Since it is often necessary to make some manual changes in the tasks of modeling archaeological objects, which necessarily requires special skills in working with complex software, as well as considerable time costs, the task was to implement an algorithm that facilitates this process. First, the PBR maps are extracted from the image, then the UV scan of the object is built, and at the end a unique PBR texture of the object is created. An extension for professional free software was created, allowing to get the desired result for the minimum number of user actions. The algorithm was tested on a number of colorless models of stones and various images. At the output, we got an object wrapped in a texture obtained from the original image. It is also possible, to make any additional cha
