Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "A Unity package is a single file that contains various Assets that can be used in Unity in a similar manner to a .zip file."

A block of code is set as follows:

Properties 
{
  _MainTex("Texture", 2D) = "white" 
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

void surf (Input IN, inout SurfaceOutputStandard o) {
  // Use the tint provided as the base color for the material
  o.Albedo = _MainTint;

  // Get the normal data out of the normal map texture 
  // using the UnpackNormal function 
  float3 normalMap = UnpackNormal(tex2D(_NormalTex, 
    IN.uv_NormalTex)); 
 
  normalMap.x *= _NormalMapIntensity; 
  normalMap.y *= _NormalMapIntensity; 

  // Apply the new normal to the lighting model 
  o.Normal = normalize(normalMap.rgb); 
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "To finally bake the lights, open the Lighting window by going to Window | Lighting | Settings. Once there, select the Global Maps tab."
