That's one way of doing it, but that's not modular at all. All the resources I posted are about modular approaches. Not necessary to use, but it is a good skill to learn, and can really help improve quality.
I finally finished my UE4 Modular Environment course with CGMA. Teached by Clinton Crumpler. it was an amazing 10 weeks course and i learned a lot. I really can recomand this course to everyone who has still problems with modular environments. I created this victorian mansion with 3dsMax, Substance Paitner, Substance…
Texture atlas, or packed texture, same thing. The modeling style is called modular, ala the Mod Facade Challenge. More modularity info here: http://wiki.polycount.net/CategoryEnvironment
Is there any chance of possibly seeing the modular components for the walls and how you made them? I am trying to get my head around modular pieces when modelling. I tend to struggle with how to breakdown things if that makes sense, like I don't know how 'modular' to go haha.
