The original model was trained on real 3D fractal renders (using Mandelbulber2). This dataset for this XL model is created using various sd15 models with the YhrnFractal1 lora.
Use strength 0.1 up to 1.0 as you wish, from a slight touch of fractal style to full fractal worlds or objects.
Most of the dataset has been creating using tags like "fractal, real, 3d, fractal style, YhnrFractalXL, photo" as the base.
Other tags like "horror, organic, metallic, nature, roots, strings, plates, strips, floating, landscape" work nice as additional prompt hints. Do not combine all at once.
For a little fractal shape control, use stuff like "sharp, smooth, spikes, fluid, straight, rough, curved, open, closed".
Have fun creating 3D fractal images!
Should work with about any XL model, real or anime. Not everything has been tested, so results can vary.
