免费 GLB 转 OBJ
本地把 GLB 转成 OBJ,适合 Blender、Maya、网格编辑、CAD 评审或交付。
先在本地把 GLB 转成 OBJ,再编辑或交付网格。
关于这个工具:免费 GLB 转 OBJ
Convert GLB to OBJ locally in your browser for Blender, Maya, CAD review, or mesh handoff. 无需上传——全部处理都在你的浏览器本地完成,兼顾隐私与速度。
常见用法
- OBJ 是很通用的网格交换格式,适合编辑和 DCC 交付。
- 部分 GLB 材质信息不一定能完整塞进单个 OBJ 文件。
把 GLB 转成 OBJ 给老工具用
下一个工具读不了 glTF 时就用 GLB 转 OBJ:Blender、Maya 和大多数老 CAD 都认 OBJ。论兼容性 OBJ 更强,论完整度 GLB 更强,而兼容性是唯一值得做这次转换的理由。
怎么转不掉东西
- 1
从 GLB 开始转
从信息最全的那个文件转。拿一个本就从 STL 转出来的 OBJ 再转,等于把损失叠了两次。
- 2
.obj 和 .mtl 要一起走
OBJ 把材质写进同目录的 .mtl,外加贴图文件。所有文件要一起交付,并保持 .mtl 期待的目录结构。
- 3
转完再验一遍
用查看器打开转出来的 OBJ,确认面数、包围盒,以及材质确实贴上了。
GLB 转 OBJ 常见问题
- 为什么转出来的 OBJ 是灰的?
- .mtl 没跟着走,或者它里面的贴图路径是你本机的绝对路径。打包成 zip,或者干脆发 GLB。
- OBJ 比 GLB 好吗?
- 不是。OBJ 读取支持更广;GLB 是单文件、贴图和动画都在里面。为了兼容性才转,不是为了质量。
- 要不要干脆转成 STL?
- 只有当去向是切片器时才这样。凡是能在 3D 编辑器里打开的目标,OBJ 保留的信息更多。
小提示
- OBJ 是很通用的网格交换格式,适合编辑和 DCC 交付。
- 部分 GLB 材质信息不一定能完整塞进单个 OBJ 文件。
