免费 4K 无缝纹理生成器

如何使用免费法线贴图生成器（分步）

A normal map stores surface direction so flat photos catch light in 3D. This guide walks through NormalMapAI’s free generator — from upload to engine ZIP — without installing software.

如何用照片制作无缝 / 可平铺纹理

Hard seams show up the moment a photo is tiled. Use edge blending, multi-scale fade and a 2×2–4×4 preview so the pattern repeats cleanly before you build normal and roughness maps.

把 PBR 贴图导入 Unity、Unreal 与 Blender

Export presets pack maps the way each engine expects. This guide covers import settings so albedo stays colored, normals stay linear, and ORM / MetallicSmoothness land in the right channels.

PBR 贴图说明：法线、粗糙度、AO 等

Physically based rendering needs a small set of textures that describe color, shape and light response. Here is what each map does and which ones NormalMapAI generates from one photo.

高度贴图与位移贴图：渲染器里差在哪

Both textures store height as brightness. Height often drives parallax or bump-style effects; displacement moves vertices. NormalMapAI exports both as 16-bit PNG to avoid banding.

法线贴图：DirectX 与 OpenGL（Y 翻转）

The only practical difference is the green channel: OpenGL stores +Y, DirectX stores −Y. Pick the right format — or an engine export preset — so bumps do not turn into dents.
