How can I apply tileable textures?
Place your decal in the upper left corner of the wall object, select Apply. then take the little handle on the left side of your decal and drag it to the right past the original right edge of your decal. What you just did was flip your decal. Now Apply and then again drag left over right. the edge that doesn’t move provides a nice seamless area. Of course you really have to pay attention to this when designing the texture or decal.
