Take a look at the cpp-tests project, with pretty much any menus that have "3D" in the name. If you want to see it online, go here, then search for the test name in the cpp-tests project to see the code.

i tried, but obj is always is red color, and it seems that the normal vector is wrong, or the vertex order is wrong, leading to the obj's face being hidden
i don't know if it's because of the glb->obj conversion, or something else

If the OBJ file is binary, then try to convert your files to C3T instead, since that is a text format. You can then view the data in it, which may help you pinpoint the problem. Compare them to any existing C3T files in the cpp-tests or other demo projects.

I'm not quite sure how many developers use the 3D functionality in Axmol, or even Cocos2d-x, so you may not receive much guidance from anyone else, and would have to look into these 3D-related issues yourself.

i looked at Bundle3D::loadObj
it seems axmol doesn't use .mtl file but only Texture
without map_Kd the mtl file has no effect
tinyobj::material_t is loaded but data is not used
is this a bug, or is axmol simply not supported?
