I´ve trained a 1.5 model on the sample images provided from bondage_v11 with about the same amount of images from latexperiment and reflective desire (latex images mostly, with some bdsm content)! that "basic model" has been merged with realisticvision 5.1 and then I´ve merged noiseoffset in, to make it "blacker" ;)
I haven´t experimented much with it, yet, just some test images that came out quite good (as you can see in the previews) so I´d say it´s obviously more a beta then a final product
Would be nice to see some renderings of others! the overall goal was to produce the images i already made without using a rather huge amount of loras (before i needed bdsm armbinders, bdsm clothes and at least a decent latex lora)
I also tried to train the model to depict "swedish collar" explicitely, while it still has the ability to depict metal collar as a different more general collar! you have to try around and play around with activation words!
