Just what the Japanese Countryside Needs
This is a model designed to create Japanese stone masonry, which is ubiquitous in mainland Japan. Stone walls make for interesting backgrounds. Unfortunately, this model is still struggling with producing stone masonry attached to castles, gates, and so on. I will update it in the future with additional training data. This model has been trained with walls head on, and diagonal, so you should be able to see walls appear in a variety of typical angles.
Types of Japanese Masonry
For reference, Japanese masonry comes in three styles. Kirikomi-hagi is finely hewn rock. Uchikomi-hagi is rough hewn, and Nozura-zumi is stacked naturally shaped rock in which masons refrain from shaping.
This model gets a little confused with regards to the types of wall - and tends toward a kind of average blend between fine hewn and rough hewn. This results in a great realistic rock wall, feel free to use these key words and experiment. It also is biased towards tall and impressive walls such as those found besides canals, castles, or both. Apologies if it does not provide the expected results, let me know and I'll do my best to address these issues.
Recommended strength:
This LoRA can produce somewhat unpredictable results, such as walls on both sides or appearing diagonally rather than facing. The lower strengths such as .1 will have the masonry still looking realistic, but subtle and just tucked into the background.
Low strength: subtle walls
Higher strength will make the walls a bigger part of the overall picture. So the strength required is up to you. However, I have found that many of the walls have a slant, and at higher strengths this slant can affect other subject matter. Generally, a strength of .1 to 1.5 works best.
