as Noren says.. if you want any texture to be independent from another you need different UVs - eg. by using a second UV set, creating them in your shader or a combination of existing UVs and some maths personally - I'd tile an asphalt texture set in world space and blend it with the unique normals using some masks or…
Agreed. But to clarify a couple of things: Modular simply means that you can assemble a bigger object from smaller, often repeating or exchangeable meshes. Your road bits are still modular, and you wouldn't tile the texure, but repeat/switch your meshes. If you want a basic setup for a freely tiling texture (so not in…
