Here is my first Lora, work in progress. Didn't found fitting Lora, so i made it myself. Captions a little bit bad, i selected several to get rid from colours (like pink, blue or purple), and opaque (tags about transparency making different results, most of generations only leg grabbing tentacles are transparent, but not all of them). However, i didn't escape strong tags, but made some progress, at least it's easyer to create transparent tentacles now. Cross tags need some tests.
Some tags and why i use it:
(gaping anal:0.7) - this is why generator can see what we want to paint under transparent object (penetrating tentacle). weights higher making gape too big or make it near tentacle (not through it).
Transparent tentacles - core idea. but it's working unstable, making tentacles pink, dickheaded, twisting, multiple penetrating same spot, small appendixes or sea creatures forms. searching for making them neutral, but now didn't make it after training.
Clouds - best background i've found yet. Helpfull cause of bright colour, light source, it's simple. most transparent tentacles are attached to background, so it's important. Often tentacles becoming the same colour as background, like blue for sky or green for forest. Also transparency working much better with day lightfull backgrounds. Don't know how about glowing yet, this might become a great addition.
Transparent_tentacle_anal - all captions contains this tag, so it might be usefull for lora triggering.
Stomach, full body, face - determinating body location, captions mostly for disembodied ass (easyer to paint and focus on the main Lora part). Generation has big weights on ass and disembodied body to focus on penetration only, so You can experiment with body determenating tags.
Tags about poses (vaginal, oral, handjob) - working not bad, i guess You can mix them with main as much as You want.
Hope this will be helpfull for You. Gonna work on it and will train again after collecting some neutral caption materials. If You have any suggestions, feel free to comment or contact me.
