You can tile UVs in the material editor. Add a TexCoord node and connect that to the texture you want to tile. You can repeat the UVs from the TexCoord Node, or you can Multiply the coordinates by a Scalar Parameter. If you make a material instance, you can edit the scalar parameter to see the texture update in real time.
I got a problem with tiling the materials. I created a few cubes, scaled them and put an texture on them. The problem is, that the material is not tiling, it just scales and looks horrible. I searched for a few hours, but the only thing, I found was the keyword “tiling-methods”, but I am not able to find this setting! I hope you can help me.
btw. please excuse my bad english
