WAN 2.1 FP16 LoRAs (NSFW)

This repository is structured to store LoRA (Low-Rank Adaptation) models for the WAN (World Animation Network) 2.1 video generation system. These LoRAs are designed to provide specialized enhancements for camera control, lighting, motion dynamics, and quality improvements for NSFW content generation.

Model Description

WAN 2.1 LoRAs are adapter models that modify the behavior of the base WAN 2.1 video generation model without requiring full model retraining. These lightweight adapters enable:

Camera Control: Dynamic camera movements, angles, and cinematic effects
Lighting Enhancement: Advanced lighting scenarios and atmospheric effects
Motion Dynamics: Improved motion coherence and temporal consistency
Quality Enhancement: Fine-grained detail improvements and style adaptations
NSFW Content: Specialized adaptations for adult content generation

LoRA models offer memory-efficient fine-tuning by adapting only low-rank weight matrices, typically requiring 50-500 MB per adapter compared to multi-gigabyte full model fine-tunes.

Usage Examples

Basic LoRA Loading with Diffusers

from diffusers import DiffusionPipeline
import torch

# Load base WAN 2.1 pipeline
pipe = DiffusionPipeline.from_pretrained(
    "wangkanai/WAN2.1",
    torch_dtype=torch.float16,
    variant="fp16"
)
pipe.to("cuda")

# Load LoRA adapter
lora_path = r"E:\huggingface\wan21-fp16-loras-nsfw\loras\wan\camera-control.safetensors"
pipe.load_lora_weights(lora_path)

# Generate video with LoRA enhancements
prompt = "cinematic pan shot of a mountain landscape at sunset"
video = pipe(
    prompt=prompt,
    num_frames=64,
    height=512,
    width=512,
    num_inference_steps=50,
    guidance_scale=7.5
).frames

# Save video
from diffusers.utils import export_to_video
export_to_video(video, "output.mp4", fps=8)

Multiple LoRA Fusion

# Load multiple LoRAs with different weights
lora_configs = [
    (r"E:\huggingface\wan21-fp16-loras-nsfw\loras\wan\camera-control.safetensors", 0.8),
    (r"E:\huggingface\wan21-fp16-loras-nsfw\loras\wan\lighting-enhancement.safetensors", 0.6),
    (r"E:\huggingface\wan21-fp16-loras-nsfw\loras\wan\quality-boost.safetensors", 0.7),
]

for lora_path, weight in lora_configs:
    pipe.load_lora_weights(lora_path, adapter_name=lora_path.split("\\")[-1])
    pipe.set_adapters([lora_path.split("\\")[-1]], adapter_weights=[weight])

# Generate with combined LoRA effects
video = pipe(prompt="your prompt here", num_frames=64).frames

Dynamic LoRA Switching

# Enable/disable LoRAs dynamically
pipe.enable_lora()  # Enable LoRA adapters
video_with_lora = pipe(prompt="enhanced prompt").frames

pipe.disable_lora()  # Disable LoRA adapters
video_without_lora = pipe(prompt="same prompt").frames

Performance Tips and Optimization

Memory Optimization

# Enable CPU offloading for lower VRAM usage
pipe.enable_model_cpu_offload()

# Enable attention slicing for memory efficiency
pipe.enable_attention_slicing()

# Enable VAE tiling for large videos
pipe.enable_vae_tiling()

# Sequential CPU offload for maximum memory savings
pipe.enable_sequential_cpu_offload()

Speed Optimization

# Use torch.compile for faster inference (PyTorch 2.0+)
pipe.unet = torch.compile(pipe.unet, mode="reduce-overhead", fullgraph=True)

# Reduce inference steps (quality vs speed trade-off)
video = pipe(prompt="...", num_inference_steps=30)  # Default: 50

# Use lower resolution for faster generation
video = pipe(prompt="...", height=384, width=384)  # Default: 512x512

# Batch multiple generations
videos = pipe(prompt=["prompt1", "prompt2"], num_frames=64).frames

Quality Enhancement

# Higher inference steps for better quality
video = pipe(prompt="...", num_inference_steps=75)

# Fine-tune guidance scale (7.0-10.0 typical range)
video = pipe(prompt="...", guidance_scale=9.0)  # Default: 7.5

# Generate longer videos with temporal consistency
video = pipe(prompt="...", num_frames=128)  # Default: 64

# Use higher resolution for better detail
video = pipe(prompt="...", height=768, width=768)

LoRA Weight Tuning

# Adjust LoRA strength for subtle or dramatic effects
pipe.set_adapters(["camera-control"], adapter_weights=[0.5])  # Subtle
pipe.set_adapters(["camera-control"], adapter_weights=[1.0])  # Full strength
pipe.set_adapters(["camera-control"], adapter_weights=[1.5])  # Exaggerated

# Combine multiple LoRAs with different weights
pipe.set_adapters(
    ["camera-control", "lighting", "quality"],
    adapter_weights=[0.8, 0.6, 0.9]
)

Installation and Setup

Install Required Packages

# Core dependencies
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121

# Diffusers with video support
pip install diffusers[torch] transformers accelerate safetensors

# Additional utilities
pip install opencv-python imageio imageio-ffmpeg xformers

Verify Installation

import torch
import diffusers

print(f"PyTorch: {torch.__version__}")
print(f"CUDA Available: {torch.cuda.is_available()}")
print(f"CUDA Version: {torch.version.cuda}")
print(f"Diffusers: {diffusers.__version__}")

Troubleshooting

Common Issues

Out of Memory Errors:

Enable model CPU offloading: pipe.enable_model_cpu_offload()
Reduce video resolution or frame count: height=384, width=384, num_frames=32
Enable attention slicing: pipe.enable_attention_slicing()
Use sequential CPU offload: pipe.enable_sequential_cpu_offload()

Slow Generation:

Use torch.compile for acceleration (PyTorch 2.0+)
Reduce inference steps: num_inference_steps=30
Ensure CUDA is properly configured: torch.cuda.is_available()
Install xformers for memory-efficient attention: pip install xformers

LoRA Not Loading:

Verify file path is absolute and correct (use raw strings: r"path")
Check LoRA compatibility with base model version
Ensure safetensors library is installed: pip install safetensors
Try loading with explicit adapter name: pipe.load_lora_weights(path, adapter_name="my_lora")

Quality Issues:

Adjust LoRA weights (typically 0.5-1.0 range)
Increase inference steps: num_inference_steps=75
Fine-tune guidance scale: guidance_scale=8.0-9.0
Improve prompt engineering (be specific and descriptive)
Check for LoRA conflicts when using multiple adapters

Video Artifacts or Flickering:

Increase temporal consistency with more frames: num_frames=128
Reduce LoRA strength if causing instability
Adjust guidance scale (lower values = more creativity, higher = more adherence)
Check for incompatible LoRA combinations
