Frequently Asked Questions
What is a bump map?
A bump map is a grayscale texture that fakes surface height detail on a 3D model without adding geometry.
How do I create a bump map from an image?
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.
What's the difference between bump and height maps?
A bump map affects shading only, while a height map can physically displace mesh surfaces in some engines.
Where can I use bump maps?
Bump maps are supported in most 3D tools and engines, including Blender, Maya, Unreal Engine, and Unity.
Are my bump maps stored on your servers?
No, your images stay on your device. The generator runs in your browser, so your work is fully private.
