    i've been experimenting with trying to get the best looking rock
    i downloaded some rock textures from this awesome free site https://cc0textures.com/list?q=rock

    on this size rock (yep, low poly) i'm using, i found tiling by 4x4 looks very natural (rock on the left)
    then i tried using its own normal map as a second (detail) normal map with tiling 10x the base map tiling (rock on right)
    i think the extra detail on the right looks great
    has anyone else played around with these parameters? what's your experience?

    also, when i downloaded the files from that website, i also got a displacement map and a roughness map, i tried putting them in various slots in the material but nothing looked good, any idea how to use?
    thanks

    PS, i think it's better not to make the secondary tiling an integer multiple of the main tiling so the detail doesn't repeat the same on each primary tile. odd numbers seem to add more randomness and helps reduce the visual tile effect

    actually if i get really close the difference is night and day with secondary map

    above is main map no tiling, secondary map tile 7 and 9 Untitled2.png
    and above is no secondary map, so it really works
