Not able to learn specular and diffuse properties

[iraj465]

Hey i trying to model objects for plastic-like objects

Input video:

Config:

{
  "ref_mesh": "./plastic-grocery",
  "random_textures": true,
  "iter": 2000,
  "save_interval": 500,
  "texture_res": [
    2048,
    2048
  ],
  "train_res": [
    1080,
    1920
  ],
  "batch": 4,
  "learning_rate": [
    0.03,
    0.003
  ],
  "kd_min": [
    0.03,
    0.03,
    0.03
  ],
  "kd_max": [
    0.8,
    0.8,
    0.8
  ],
  "ks_min": [
    0,
    0.08,
    0
  ],
  "ks_max": [
    0,
    1,
    1
  ],
  "dmtet_grid": 128,
  "mesh_scale": 2.4,
  "lock_light": true,
  "laplace": "absolute",
  "laplace_scale": 5000,
  "background": "white",
  "display": [
    {
      "latlong": true
    },
    {
      "bsdf": "kd"
    },
    {
      "bsdf": "ks"
    },
    {
      "bsdf": "normal"
    }
  ],
  "out_dir": "grocery"
}

This is the output:

@jmunkberg i found that the textures are washed out, what can be done to model the textures accurate to the video itself?

During first pass the textures are blurry, but still okay

But even during the second pass, the textures haven't improved and are very blurry
