 * **Sphere**: Spherical coordinates (difference of the normal at the pixel by the camera normal).
 
-The value of every pixel of the texture is multiplied by the original param. This means that if a texture is loaded for diffuse, it will be multiplied by the color of the diffuse color parameter. Same applies to all the others except for specular exponent, which is replaced.
