The weird color and bad appearance results

[A-pril]

Hi~ It's great work. But I wanna use this code to generate texture only. And the results are all very bad just like the below.

The config is here:
{
"mode": "appearance_modeling",

"out_dir": "nascar-0",
"text" : "A next gen nascar in red",

"ks_max" : [0, 0.7, 0],
"display": [{"latlong" : true}, {"bsdf" : "kd"}, {"bsdf" : "ks"}, {"bsdf" : "normal"}],
"envmap": "data/irrmaps/mud_road_puresky_4k.hdr",
"env_scale" : 2.0,
"train_background": "black",
"validate" : true,

}
