Upload any grayscale or color image, adjust the strength slider (0.1-3.0), optionally invert Y for DirectX compatibility, choose tiling (1x1, 2x2, or 3x3), and preview the result in both 2D plane view and 3D sphere/cube preview. Use advanced settings like detail scale, blur, sharpen, and levels adjustment for fine-tuning. Click 'Download PNG' when satisfied with the result.
