V1.0

The same file can be used for both high and low noise due to dual training. The dataset was also updated to be 8 FPS which can overemphasize the motion at times. It's far from perfect but the transparency should be better than v0.3. If you are having issues with jittering, try lowering the weight(s) and/or using a different LoRA for the main high noise motion. If the transparency is "stuck" you might either have the high noise weight too high, a conflicting low noise LoRA, or the position/penetration type is just too unique. Otherwise a weight of 1.0 should be fine for both high and low noise.

This is best used as a NSFW enhancer for slime girls rather than a standalone motion LoRA.

I got tired of waiting 10-15 minutes for a slime girl animation only to be disappointed by the transparency not getting animated right. In that regard this was originally meant to be similar to Translucent Penetration, but there is also some builtin motion enhancement.

The trigger word is slime_girls but you might not need it. A simple prompt like this works well enough:

He is enthusiastically fucking her ass. Detailed transparency distinctly shows his penis moving inside her body. She is very pleasured and expressive.

Don't describe the image for I2V unless it's getting important details wrong. Wan 2.2 works best when the prompt describes the actions in a straight and to the point manner.

For best results I would recommend using with SmoothMix Animations XXX (or something equivalent) and a checkpoint with good NSFW understanding. I usually use DaSiWa WAN 2.2 I2V 14B. The starting image also needs to have good transparency or it might not get the effect right.

Bonus tip - if you are using the lightspeed version of DaSiWa or another checkpoint that has the Lightx2v LoRAs merged, you can stack a high noise Lightx2v LoRA on top of your high noise LoRAs to boost the motion. Start with a weight of ~0.5. Higher weights give stronger boosts with higher risk of quality degradation and/or nonsensical movements.
