WAN 2.2 I2V - Edible Anuses

This is a fairly simple low-noise only anus lora. The goal was to generate realistic looking anuses in the right spot, that aren't massively gapped or abused, when one is not visible in the starting image. In particular this was aimed to work in conjunction with my pov face sitting lora.

Prompt is simply needs to include the word anus somewhere for this to kick in. However, WAN seems to often have no idea where to put buttholes so the following helps a lot:

A woman presents her anus. Her anus is directly above her vulva.

Obviously if the subject is on their back describe the anus as being below the vulva. The lora should be able to add some specifics around what the anus looks like such as:

a small round anus

The anus is pinkish in color

Her anus is centered, slightly puckered

Given the training material for this often had both a anus and vulva, you can use it to control the shape and color of the vulva too but I've not tested that extensively. Critical keywords are vulva and labia in terms of prompts.

Testing

I tested this using base WAN 2.2 I2V Q8 and the lightning loras. Nothing else in the mix so i could get as good an idea as possible of what WAN knew vs was introduced by the lora. Here are some side by side comparison of the final frames. Left is no lora right with with lora(weight ranging from 1 to 1.5)

No Lora:

Lora at Weight 1.0

Lora at Weight 1.5

Lora at Weight 2.0:

Clearly by the end we're starting to get an actual butt hole. Bear in mind the starting frame for this video is this:

That said i think it could still do with some more training, but its not a bad start imo.

Dataset and Training info.

Input data set was 167 videos all pulled directly from reddit (you can guess the name of the subreddit). Batch trimmed to just the first 3 seconds and capped to 16 fps.

Data set was auto-captioned using JoyCaption Beta and DarkAges 70b.

Training was done at 512 for 30 epochs, 1 repeat and batch size 2 using diffusion pipe. LR was 2e-4.

As always still not sure i know what i'm doing yet and open to feedback!
