This is a replica of the Saint Paul Cathedral located in London, made entirely in blender and it uses a full set of tileable textures and trim sheets (for the most part, some assets contain their own texture sets) with a full set of vertex painting to blend 3 types of textures together for each material.
Thanks a lot! the whole model, interior/exterior took about 3 months or so to be completed, and the material rendering didn’t take too long, it’s real-time.
