This is a Stable Diffusion model fine-tuned on Starcraft terrain images on the Space Platform tileset with DreamBooth. It can be used by adding the instance_prompt: isometric scspace terrain

It was trained on 32x32 terrain images from 265 melee maps including original Blizzard maps and those downloaded from Battle.net, scmscx.com and broodwarmaps.net.

Run it on Huggingface Spaces:

https://huggingface.co/spaces/wdcqc/wfd

Or use this notebook on Colab:

https://colab.research.google.com/github/wdcqc/WaveFunctionDiffusion/blob/remaster/colab/WaveFunctionDiffusion_Demo.ipynb

In addition to Dreambooth, a custom VAE model (AutoencoderTile) is trained to encode and decode the latents to/from tileset probabilities ("waves") and then generated as Starcraft maps.

A WFC Guidance, inspired by the Wave Function Collapse algorithm, is also added to the pipeline. For more information about guidance please see this page: Fine-Tuning, Guidance and Conditioning

This model was created as part of the DreamBooth Hackathon. Visit the organisation page for instructions on how to take part!

Description

Usage

First clone the git repository:

git clone https://github.com/wdcqc/WaveFunctionDiffusion.git

Then create a Jupyter notebook under the repository folder:

python

# Load pipeline
from wfd.wf_diffusers import WaveFunctionDiffusionPipeline
from wfd.wf_diffusers import AutoencoderTile

wfc_data_path = "tile_data/wfc/platform_32x32.npz"

# Use CUDA (otherwise it will take 15 minutes)
device = "cuda"

tilenet = AutoencoderTile.from_pretrained(
    "wdcqc/starcraft-platform-terrain-32x32",
    subfolder="tile_vae"
).to(device)
pipeline = WaveFunctionDiffusionPipeline.from_pretrained(
    "wdcqc/starcraft-platform-terrain-32x32",
    tile_vae = tilenet,
    wfc_data_path = wfc_data_path
)
pipeline.to(device)

# Generate pipeline output
# need to include the dreambooth keyword "isometric scspace terrain"
pipeline_output = pipeline(
    "isometric scspace terrain, corgi",
    num_inference_steps = 50,
    wfc_guidance_start_step = 20,
    wfc_guidance_strength = 5,
    wfc_guidance_final_steps = 20,
    wfc_guidance_final_strength = 10,
)
image = pipeline_output.images[0]

# Display raw generated image
from IPython.display import display
display(image)

# Display generated image as tiles
wave = pipeline_output.waves[0]
tile_result = wave.argmax(axis=2)

from wfd.scmap import demo_map_image
display(demo_map_image(tile_result, wfc_data_path = wfc_data_path))

# Generate map file
from wfd.scmap import tiles_to_scx
import random, time

tiles_to_scx(
    tile_result,
    "outputs/generated_{}_{:04d}.scx".format(time.strftime("%Y%m%d_%H%M%S"), random.randint(0, 1e4)),
    wfc_data_path = wfc_data_path
)

# Open the generated map file in `outputs` folder with Scmdraft 2
