How to blend texture?

I normally put texture on my objects in mudbox, but this object is just too big to do that,


As you can see i took a picture from the internet of some sand, is there anyway i can kind of blend it togheter? so i cant see the line where the picture stops?

sorry for bad english

I would recommend you to just search for “seamless” textures, because then everything will look correct. Either edit the existing texture or just download a new one
