It might be a little bit late but it can help someone else. I have been working with min3d and I had the same problem, then I found out why I had the black screen :

1) Check the size and position of your object.

2) Check your mtl file Try to use these values :

Ns 96.078431 Ka 1.000000 0.000000 0.000000 Kd 0.640000 0.640000 0.640000 Ks 0.500000 0.500000 0.500000 Ni 1.000000 d 1.000000 illum 2

3) Otherwise check youf file names and links : When you export your objects from Blender, your original file names are for example my_model.obj and my_model.mtl. Loading them on android imposes you have different names (without the extension), try calling them : my_model_obj and my_model_mtl.

The problem with you is maybe because you did not rename the .mtl file inside the .obj file.

Just check the .obj file line mtllib my_model.mtl and replace it by mtllib my_model_mtl

Works fine for me

Try adding light to the scene

Light light = new Light();
scene.lights().add(light);
