If i want to export gltf（jme mesh） How can i do

i want to export gltf by jme

You can’t.

JME can import GLTF. JME can’t export anything.

im not sure why you need it, since in 99,99% cases need just import, the only case on mind is that you are doing some model Editor.

Anyway You would need write exporter yourself in this case, because its not needed for a games to export models, only to import. (so like Paul said there is build-in import only, because export is not needed)

Possibly exporting to .OBJ would be easier, then you can use blender to convert it.
Here’s an old thread you could use for inspiration:

Export mesh to .obj

How it is possible to save a mesh to a .obj file? My problem is I’ve a easy model. I have only the vertices, indices and normals. No lights, material, ambient and so on. If there is no exporter, then someone can help me writing an obj file. I have not so much knowledge about 3d programming.

你是只有j3o文件想导出obj？

@icyboxs

you only have j3o files and want to export obj

Make a jme application that:

1. loads the j3o
2. get the Mesh object
3. iterate over the mesh buffers like the code in the link
4. write output to a text file (.obj)

Load .obj with blender and export as .gltf

[icyboxs]

That’s a good way to go

.obj dont support animations or morph shapes or PBR material

while .gltf do. So it would be ok only if model have no animations.
