Why can't I load a .OBJ file into Python Ursina?

I am using the python Ursina engine. I want to import a .OBJ file, but it never works, yet no errors are raised. I have tried:

from ursina import *
from ursina.mesh_importer import *

app = Ursina()

model123 = load_model('model123.obj')
model123Entity = Entity(model=model123)
    
def update():
    move()

EditorCamera()
app.run()

I have also tried it without the .obj ending. Any help?

I have now tried:

from ursina import *
from ursina.mesh_importer import *

app = Ursina()

model123 = load_model(obj_to_ursinamesh('model123.obj'))
model123_Entity = Entity(model=model123)

app.run()

I get the error:

AttributeError: 'str' object has no attribute 'glob'
AL lib: (EE) ALCwasapiPlayback_mixerProc: WaitForSingleObjectEx error: 0x102
Solution

  • The issue is triangulation. The models faces must only be triangles. You can do this in Blender or other 3d software of that such type. I got this information thanks to Pokepetter on Github, at this issue.

    For example, consider using Blender, or other software similar, to create your models and use the triangulate modifier on meshes to make them compatible with Ursina Engine.
