Trouble assigning material

On my ongoing quest to make an electric covet, I ran into the following issue:
I edited the games original covet Rear bumper to have no exhaust hole.
I've renamed the bumper and got it in-game, but the textures don't want to be assigned.
It just looks like this:


Here's my main.materials.json code:

Code:

{
  "hatch_bumper_R_e : {
    "name" : "hatch_bumper_R_e",
    "class" : "Material",
    "persistentId" : "5e1d336c-0df5-4a15-aa0c-15623dbhrtjt",
    "Stages" : [
      {
        "colorMap" : "vehicles/common/null.dds",
        "normalMap" : "vehicles/hatch/hatch_bumpers_n.dds",
        "pixelSpecular" : true,
        "specularMap" : "vehicles/common/null.dds",
        "specularPower" : 128,
        "useAnisotropic" : true
      },
      {
        "colorMap" : "vehicles/hatch/hatch_bumpers_d.dds",
        "normalMap" : "vehicles/hatch/hatch_bumpers_n.dds",
        "pixelSpecular" : true,
        "specularMap" : "vehicles/hatch/hatch_bumpers_s.dds",
        "specularPower" : 32,
        "useAnisotropic" : true
      },
      {},
      {}
    ],
    "alphaRef" : 0,
    "dynamicCubemap" : true,
    "mapTo" : "hatch_bumper_R_e",
    "materialTag0" : "beamng",
    "materialTag1" : "vehicle",
    "translucent" : true,
    "translucentBlendOp" : "None"
  },

The bumper jbeam is attached!
I really hope I can get some help.
