I can't render .obj files correctly

[Progolue]

I am using blender to make some models and try to add entity :
scene.add_entity( morph=gs.morphs.Mesh( file="meshes/conical_flask/conical_flask.obj", scale=0.3, pos=(0.0, 2.0, 0.0), euler=(90,0,0), ), )
the folder has .mtl and .obj file:
conical_flask.mtl:
newmtl glass Kd 0.800000 0.800000 0.800000 Ks 0.500000 0.500000 0.500000 Ke 0.000000 0.000000 0.000000 Ni 1.520000 d 1.000000 illum 2 Pr 0.000000 Pm 0.000000 Ps 0.000000 Pc 0.000000 Pcr 0.030000 aniso 0.000000 anisor 0.000000 Tf 1.000000 1.000000 1.000000
conical_flask.obj:
mtllib conical_flask.mtl o conical_flask usemtl glass v 0.000000 1.231083 -0.146523 .....
I can render the example obj such as bathhub or boat, but i can not render my material correctly.Thanks for helping me.

Could you upload your file so we can check?

conical_flask_mtl.txt
conical_flask_obj.txt
It seems that the two formats aren't supported for upload, so I converted them into a text file format. Thank you very much!
