Hearthstone SD 1.5 LoRA

This repository contains a Stable Diffusion 1.5 LoRA adapter trained for Hearthstone-style card artwork generation as part of the COMP 646 HearthGen project.

Files

• pytorch_lora_weights.safetensors: Diffusers-compatible LoRA weights.

Intended Use

This model is intended for research and course-project reproduction. It is used by the HearthGen pipeline to compare:

• Stable Diffusion 1.5 text-only generation
• Stable Diffusion 1.5 with reference conditioning
• Stable Diffusion 1.5 + Hearthstone LoRA text-only generation
• Stable Diffusion 1.5 + Hearthstone LoRA with KG-retrieved reference conditioning

Loading With Diffusers

import torch
from diffusers import StableDiffusionPipeline

pipe = StableDiffusionPipeline.from_pretrained(
    "stable-diffusion-v1-5/stable-diffusion-v1-5",
    torch_dtype=torch.float16,
).to("cuda")

pipe.load_lora_weights("comp646/hearthstone-sd15-lora")

image = pipe(
    "hsart Hearthstone card art, Warrior minion, iron armor, glowing embers",
    num_inference_steps=30,
    guidance_scale=7.5,
).images[0]

Dataset

The LoRA was trained from the project artwork dataset:

• comp646/hearthstone-art-512

The dataset contains Hearthstone artwork crops and metadata for project reproduction. Artwork and Hearthstone IP belong to Blizzard Entertainment; this model is distributed only for academic project use.
