I know there is a few of stained glass lora out there, but it seems it's quite difficult to get people or animals inside the glass (tend to be a person in front of a stained glass); this lora aims to tackle this specific problem.
This lora is underbaked, it can work ranging from 0.9-2.5, depends on what other lora you put into. For example, if your lora is anime based, with line arts, you will need less of this stained glass lora, something around 0.9-1.5; vice versa.
If you want the simpler look, go for higher weight, lower weight will render your character more detailed and less glass art looking, give it some try and adjust the weight accordingly.
Finally as always, go break some eggs, have fun!
