How to add specular map,bump map and colour texture in one object using x3d?

In order to add color/light to an object you can use Appearance node:

Appearance { 
  exposedField SFNode material          NULL
  exposedField SFNode texture           NULL
  exposedField SFNode textureTransform  NULL
}

The material field can be a Material node:

Material { 
  exposedField SFFloat ambientIntensity  0.2         # [0,1]
  exposedField SFColor diffuseColor      0.8 0.8 0.8 # [0,1]
  exposedField SFColor emissiveColor     0 0 0       # [0,1]
  exposedField SFFloat shininess         0.2         # [0,1]
  exposedField SFColor specularColor     0 0 0       # [0,1]
  exposedField SFFloat transparency      0           # [0,1]
}

Or, if you want to add texture to your object you can use texture or textureTransform fields.
