Repeating Image Textures to UV map At the moment I´m working on a model with many different Image Textures.
To publish it on Sketchfab I need UV Maps that fit the texture. 
My unwraped Object is however bigger then the texture itself. 

How can I make a UV Map out of a repeating Image Texture?
Do I need to manually reapeat it in Photoshop unil it fits?

(I know that you can press Ctrl+A and Ctrl+P to make it fit to the texture. The mappping changes though)
Try pressing S after highlighting your mesh in the UV editor to scale it downward. There should also be a repeat image setting somewhere in the UV editor.
