Wallpaper Sirpi 16160 - 6K Material Texture

This appears to be a product description in Russian for a 3D model of an architecture project called "Sirpi" or possibly a nickname. Here's a breakdown: * The description starts with saying that it is an accurate rendering of a specific scene using Corona Renderer (a render engine for architectural visualization). It has the original shader and no texture distortion, implying a very detailed level of information preservation during export. * Technical specifications are listed: + Resolution: 6500 x 6500 pixels + Real-world size: 55.03 meters (width) x 55.03 meters (height) + Density per square inch (or more precisely DPI): 300 DPI, which is an incredibly high level for printing purposes, but normal for high-end 3D rendering and archiving of images. * The text goes on to recommend not to render Corona scenes below version 1.5 for optimal output since PBR parameters (PBR - physically-based rendering) would be compromised by this decision. However, users need a very specific setup that works for their workflow for PBR rendering to fully utilize its advantages without visual differences. Users must then consider setting materials with PBR shaders within the limits allowed before and during conversion in Corona engine from their native model. Some interesting points are made regarding the design intent: * No note is provided as to who owns these copyrights - there isn't anything visible outside which allows this type of scan. Given the high-quality images described and what you can observe, if a client bought such a rendering they'd presumably expect some pretty close approximation to a finished scene with real-world materials or PBR applied - otherwise this kind of information might indicate some very specific software issues related only in how an internal model looks.
