[1.12.2] obj model. Green instead of gray

[Lofectr]

I created obj (Model), mtl (Material), png (Texture) files in Blender.
In blockstate I wrote it like this:

{
  "forge_marker": 1,
  "defaults": {
    "custom": { "flip-v": true },
    "model": "lg:lofectr_block.obj"
  },
  "variants": {
    "normal": [{}],
    "inventory": [{}]
  }
}

The problem is that the gray on the texture in the game turns to green!

 

Help, what could be the problem? And how to fix it?
