Shows up as black when i edit the material map

[torchesburn]

The map shows as black when i apply it

    const {name, shader, vectorProperties, textureProperties, floatProperties} = materialProperty;
    console.log(materialProperty);
    if (shader === 'VRM/MToon') {
      const objects = _findMaterialsObjects(o.scene, name);
      for (const object of objects) {
        const newMaterial = new MToonMaterial();
        newMaterial._debugMode = true;
        const oldMaterial = object.material;
        Object.keys(vectorProperties).forEach(key=>{
          newMaterial[key] = vectorProperties[key];
        });
        Object.keys(textureProperties).forEach(key=>{
          newMaterial[key] = textureProperties[key];
        });
        Object.keys(floatProperties).forEach(key=>{
          newMaterial[key] = floatProperties[key];
        });

        newMaterial.map = oldMaterial.map;

        This is how the materialProperties look : 

        ```json
