This LoRA can generate unique iris patterns. 3D artists should be able to use this to texture eyes.Eye colors you can prompt for: Blue, Gray, Hazel, Brown, Green. You might have to edit the colors afterwards if you want something more intense, as this model is based on natural human photos.For the flux version these settings seem to work well for me:1024px x 1024px size upscaled with hiresfix/latent upscale at 1.5x CFG 2 20 steps euler / simple prompt: airis, green iris eye texture, a perfectly round black pupil centered in the texture of an iris with a circular white background, high quality render of a flat eye material, sharp focus<h3 id="for-the-sd-1.5-version-use-the-default-stable-diffusion-1.5-model-(finetuned-models-have-weird-effects-on-the-iris-texture)-eowxcklv2">For the SD 1.5 version, use the default Stable Diffusion 1.5 model (finetuned models have weird effects on the iris texture)</h3>Trained on a dataset of 512x512 and 768x768 images, although it seems to prefer generating at 512x512 and using hires fix. (Latent upscale at 0,6 denoise works well, although you can also use ESRGAN at 0,25. Different hires methods will change the patterns depending on what you're after.)Generating at 768px will sometimes give results which aren't centered.Trained on base v1.5 and tested with Euler A sampling method. Your results may vary if you use something else, but feel free to experiment.
