[Semi-Experimental] Hunyuan NSFW + furry

A lora for enhancing NSFW content in hunyuan and adding (hopefully) better support for furries.

I consider this lora experimental as it might be difficult to prompt and can produce bad anatomy even with prompts that usually work.

The lora can be used at full strength on it's own, and probably also works in combination with other loras. The lora adds information about sex positions and some other nsfw concepts. Furries and aims to retain the ability to generate videos of realistic humans.

Hunyuan supports basic nsfw and furries out of the box, this lora aims to enhance motions, improve knowledge of different sex positions, etc.

This was my first time using the civitai lora trainer for a video model. But it was 5k buzz to train this model for 20 epochs. Which is a pretty good price I'd say.

Most previews are deepthroat because it usually has more motion, I haven't figured out the proper settings and prompts to get good results with other positions yet. I'm usually not getting a lot of movement.

Next version

For the next version, I want to train on runpod, and use multiple-overlapping context (which I'm fairly sure civitai doesn't use in the online training) to get better movements and more varied results. If anyone has runpod credits they are willing to donate for this training, it would be much appreciated. Just send me a dm on here if you have some runpod credit you want to donate. I am currently running low so I opted for the civitai trainer for this model.

Prompting

Prompts in the training data were captioned manually by describing the type of video "2d animation, 3d animation, real video", and each character was described by species and then characteristics, including humans, although humans were described simpler "A human man" and then details vs "an anthro fox" or "a furry fox" and then those details. Prompting with natural language should work,
Anthro/furry should be somewhat interchangable
Non-furry content should work, just describe "A human woman" instead of "an anthro [species] woman" for example, avoid ambiguity as I have not tested whether the character are inherently human or furry when not specified. So I recommend just describing it.

You can prompt for fast movements or a medium pace, it is not guaranteed to follow your prompts though. In current testing it seems that furry characters tend to have less movements than humans, as I switched a furry prompt to human and the character in the next gen started moving way too much.

I have not tested prompting extensively yet, there might be some "magic phrases" that help enhance things, I suggest experimenting with different prompts if you can

Common mistakes and workarounds

The model can still sometimes provide not enough motion, you can prompt for more motion though. Make sure you describe the direction of the motion as well.

The model might not get the anatomy proper on every gen, so in some cases you might want to include some details like breasts, face, eyes, etc. in the prompt. This will help a lot to prevent the anomalies.
