Textures rendering slanted

[mmoyes]

Trying various versions of planes to render a simple grid texture. They are all appearing slanted as below

texture_image = Image.open(texture_file)
texture = pyrender.Texture(source=texture_image, source_channels='RGB' )
material = pyrender.MetallicRoughnessMaterial(
    metallicFactor=0.0,
    roughnessFactor=1.0,
    baseColorTexture=texture
)
mesh = pyrender.Mesh.from_trimesh(trimesh.load(mesh_file), material=material)
mesh_node = pyrender.Node(mesh=mesh, matrix=np.eye(4))
scene.add_node(mesh_node)
