Problem with tileset

I have a lot of images used for tilemap.I used texturepacker to merge images to a big image.I choose the ue4 format.Then I got a paper2dsprites format file,I import it into ue4 editor, and I got some sprite and a sprite sheet.How can I use them in tilemap, or create a tileset from them.

Unreal website has a video tutorial on how to create paper2d stuff. I’m not sure if they showed much about making tilesets but I think they showed how to do it basically.
