Frequently Asked Questions
A bump map is a grayscale texture that fakes surface height detail on a 3D model without adding geometry.
Upload any image, adjust the strength slider (0.1-2.0), optionally invert height, choose tiling (1x1, 2x2, or 3x3), and preview the result in both 2D plane view and 3D sphere/cube preview. Use advanced settings like contrast, brightness, blur, and levels adjustment for fine-tuning. Click 'Download PNG' when satisfied with the result.
A bump map affects shading only, while a height map can physically displace mesh surfaces in some engines.
Bump maps are supported in most 3D tools and engines, including Blender, Maya, Unreal Engine, and Unity.
