Hi everyone!

I'm pretty new to Maya and I'm trying to think of the best way to map my UVs in Maya and apply textures in C4D. I attached the look of the textures I'm trying to achieve. I have a building with a bunch of separate objects I want to apply different materials to. For every object I'd like to apply an individual texture to but in addition I want to apply an overall texture (the grafitti). Now I'm wondering how to go about it. Combining and laying out the individual UVs?

I hope my question is understandable... I basically am trying to apply individual texture to individual objects and have an overall texture go across all of them. Any help is appreciated :0 Thank you guys already!!
