Good Morning SDS,

select you’re materials and paintbrush> go to landscape backgrounds> right click select add material> then select the pic beside the word texture which will pop up an other box and then select select,(see pic beelow) and that will take you to you’re folders on your computer then you just have to find the folder you saved it to. Sometimes you have to change the type of file you are looking for if you didn’t save it as a jpeg.
