This is an Illustrious lora for rounded style Brutalist buildings. By rounded I mean buildings with curved sides, cylindrical shapes, rounded shapes, spherical shapes, and similar attributes on the whole or parts of the structure.
This set of architecture loras annoyed me to no end. I had to remake them two times. As it turns out the term 'brutalism' forced the look to make the usual typical boxy shapes instead of the rounded ones in the sample pictures for whatever reason. Also, when it did make rounded shapes it tended to hyper focus on the few sample pictures of proposed rounded structure from above. In the end the one that worked came from removing the sample pictures of the rounded structures from above along with any other with a circular shape, as well as changing the prompts. I just hope people like the loras.
A weight of 1 to 1.5 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 3.5 to 7.5.
Prompts for this lora are ( BruRouBui, architecture, curved buildings, ).
