(ALL previews are I2V. V2 previews made from lazy Chroma outputs and some others I quickly found on CivitAI and Booru images. Most previews are single-shot gens but some were selected as the best of 2~3 generated samples)This LoRA is mostly meant to animate good sexual input images (I2V) with basic sex animations using very simple and short prompts and/or to assist other motion-specific loras.This LoRA wants sex. It wants it so much that sometimes it gives you 'ok' animations even without a prompt. Its extremely biased in that regard so its really not good for advanced use cases such as changing characters positions or scenes.If you give it a sexual scene input image that you can tell with just a glance 'what kind of movement the characters should be doing' - than this LoRA should be able to figure that movement on its own with just the correct trigger words.Audio: not trained at all. It contains audio layers from other loras merged together then injected into this one.V1: may be better at animeV2: better at realism, less over-fitting overall and broader knowledgeTerminology: penis/pussy/fellatio/insert instead of dick/cock/vagina/blowjob/penetrate<h3 id="trigger-words-with-notes-(colored-by-how-good-the-model-is-at-it-in-a-i2v-context):">Trigger words with notes (colored by how good the model is at it in a I2V context):</h3><ul><li>having sex (this one is powerful due to its versatility)</li><li>having sex in the cowgirl/reverse cowgirl/congress/reverse congress/mating press/missionary/doggystyle position (if only 1 of these scenes exists in the input image than you should use this instead of just 'having sex')</li><li>having sex while lifted in the air (for scenes where the female's legs are in the air and should dangle around during sex)</li><li>performing fellatio (not very good. you should probably pair it with a fellatio-exclusive lora)</li><li>performing a handjob with her right/left hand</li><li>performing a handjob with his right/left hand on his own penis (male masturbation.

I believe what I tried to accomplish may be possible at rank 256 with batch_size = 16 training but that's something I can't do.</li><li>In I2V mode this lora will ignore most of your prompt if its not something in the available trigger words. It highly depends on the input image and prompt but this can be heavily mitigated by not using distillation or reducing it and using CFG&gt;1.</li><li>Camera panning bias. It likes to move the camera around a little even when not prompted for it. Can be mitigated with negative prompting - see 'Extra trigger words' section.</li><li>Breast movement bias so strong it may cause flat chests to move when they should not to the point it may even affect males depending on the input image and your prompt. May be slightly mitigated with negative prompting + CFG&gt;1.</li><li>Cowgirl sex scenes with only the woman moving are very difficult to generate due to the lora's 'having sex' bias which in turn means 'man thrusting a penis inside a pussy' - as far as the lora understands it. This happens even without mentioning 'having sex' in the prompt.</li><li>Trained on very, very little anal sex data so it may hurt anal animations a bit. V1 probably does this more than V2.</li><li>Cant draw good genitals from scratch (T2V).</li></ul><h3 id="recommended-workflow-info:">Recommended workflow info:</h3><ul><li>Option A (RECOMMENDED): 3-stage workflow with input image proportionally resized to a max dimension of 512.</li><li>Option B: 2-stage workflow with input image proportionally resized to a max dimension of 1024.</li><li>For input images with very complex backgrounds: use Option B, otherwise stick to Option A. Doing Option B helps avoiding unwanted motion of background objects and stuff because LTX sometimes does that if it does not fully understand the input. But this lora performs the best motion in 512px buckets so avoid Option B.</li><li>For better I2V results avoid distillation or set it to just 25% + CFG=1.5 + 12~16 1st stage steps (2nd stage steps should be 75% of stage1 and 3rd stage should be 50%)</li></ul>
