Description

When I render my object with a texture file, the texture does not appear in my output image.

However, when I replace my object file with a built-in shape like sphere, the texture appears.

Here is link to the obj file and the texture files.

Steps to reproduce

import mitsuba as mi
import drjit as dr
import numpy as np
import matplotlib.pyplot as plt
import os
mi.set_variant('scalar_spectral_polarized')
from mitsuba import ScalarTransform4f as T

sensor = mi.load_dict({
    'type': 'orthographic',
    'to_world': T.translate([0,0,-20]),
    'sampler': {
        'type': 'multijitter',
        'sample_count': 64
    },
    'film': {
        'type': 'hdrfilm',
        'width': 1032,
        'height': 780,
        'pixel_format': 'rgb',
        'rfilter': {
            'type': 'gaussian'
        }
    }

})

integrator = mi.load_dict({
                    'type': 'path',
            },)
bsdf = {
    'type': 'diffuse',
    'reflectance': {
       'type': 'bitmap',
       'filename': '../scene/textures/metalplate_2-1K/metalplate_2_basecolor-1K.png',
    }
}
shape = mi.load_dict({
    'type': 'obj',
    'filename': f'../scene/meshes/DiLiGenT-obj/goblet.obj',
    'bsdf': bsdf,
    'to_world': T.translate([0,-0.5,0]).rotate(axis=[1,0,0], angle=-70).scale(0.01),

})
scene = mi.load_dict({
    'type':'scene',
    'integrator': integrator,
    'sensor': sensor,

        'light': {'type': 'constant'},
        'object': shape,
    'polarizer': polarizer
})
image = mi.render(scene)
bitmap = scene.sensors()[0].film().bitmap().split()[0][1]
