DOWNLOAD NEGATIVE EMBEDDING HERE FOR BEST PERFORMANCE.

This is Aether Lux, a Lexica-inspired 2.1 model, trained on synthetic data. Images are preferably generated with a base side of 768px, and for general purpose, Euler works well. For photorealism: DPM++ SDE Karras is the best choice in my experience.

The model is accompanied with a negative embedding, lux_np. You need this one applied to the negative prompt to make sure that the model functions at its very best. You place the file in the Embeddings folder within your Stable Diffusion installation (usually stable-diffusion-webui\embeddings).
