The structure of the museum building uses shader graph materials using Triplanar. Because the structures are large and complex, it is difficult to prepare appropriate images. Triplanar maps images appropriately.
However, images of surfaces diagonal to the X, Y, and Z axes are synthesized depending on the angle, and while this is not a problem for textures such as rock surfaces, textures with distinct patterns result in an unnatural image.
The degree of compositing of diagonal surfaces can be adjusted using the Blend parameter, which eliminates the unnaturalness of the compositing, but the image ends up being stretched horizontally.
A compromise can be made for the exterior walls, etc., but the walls in the exhibition room are noticeably stretched, so we divided the materials and modified the coordinates passed to Triplanar to be rotated so that they are oriented correctly depending on the orientation of the exhibition room.
