Tiling texture question

dinmeolas

I know this is painfully newbish but havent touched 3d in a couple years and needing to relearn. I will be creating textures in substance, alchemist and quixel mixer. And using in maya and Unreal. 

When I create a texture that is plain and clean, say a brick wall, I can tile it and it looks fine. yet very unreal and boring. So I would like to weather it and dirty it up so it breaks up the unnatural look and lends it some realistic character. 
But, that texture will need to tile to fill the space and any imperfections will also tile and create a pattern. So my question is, what do I need to do to use my textures in tiling where I dont get this repetition? How do you guys apply a nice realistic texture to say a wall and it doesnt look fake?
I hope I phrased that properly, thanks in advance.

you could have 2 materials and vertex blend between them. Like a dirty/damaged version, and a cleaner version and then blend them together with masks and vertex color, allowing you to paint in variation non uniformly. or something like concrete over bricks and chip away the concrete to expose brick etc. 

There are lots of vertex blending tutorials on youtube

You might be looking for vertex painting and material layering in UE4.

Also, these Substance Day at GDC 2019 videos might help you. The folks at Ubisoft share their insights on how they handle their materials:

Thanks Pixelmasher.....I have experimented with layered texturing when its appropriate and thats pretty good. For just a stone or brick wall that didnt have plaster or anything  I was out of ideas pretty quick. When I can I like to use Spsm s in Substance but the selection I have isnt always right for what I want to create.  I considered Photoshop but havent seen that I can load a texture in a brush and paint it on. I think the vertex blending is a great idea, much appreciated.
Thanks Gabmeister, Assassins Creed Odyssey is what got me wanting to do 3D again, their environments are amazing. Thanks for the links will watch those tonight.

Thanks for the video links, mate. Very informative. I have been learning more into games workflow even for offline rendering. No need to be using very high texture res when with smart techniques u can create very realistic looking texturing.
