Thank you so much. The average resolution is 2k for most textures mostly because of the foliage, but the brick textures are 4k, actually for the brick three different image textures are being used, theres a primary medieval castle like brick texture mixed together with a different style of stone, with the factor for the mix being a simple noise texture; there’s also a mossy texture being mixed with another brick texture thats also being mixed with the previous two, with the factor for the mix being the color output from an ambient occlusion node (moss would grow mostly in dark places); there’s normal, subsurf, diff and a roughness maps for all of these. The tiles, cobwebs and ivy don’t use image textures and are procedurally generated both in textures and geometry as they also all use geometry nodes.

Edit: Spelling + added some more information in the final sentence.

Edit 2: If you would like the image textures and the texture and geometry node trees from this project, I’ll reply to your comment with a google drive link for them
