Description

Add a vector material property.

	// Draws 3 meshes with the same material but with different colors.

var aMesh : Mesh; var aMaterial : Material = new Material(Shader.Find("VertexLit"));

function Update() { var materialProperty : MaterialPropertyBlock = new MaterialPropertyBlock();

// red mesh materialProperty.Clear(); materialProperty.AddVector("_Color",Vector4(1,0,0,0.5)); Graphics.DrawMesh(aMesh, Vector3(0,0,0), Quaternion.identity, aMaterial, 0, null, 0, materialProperty);

// green mesh materialProperty.Clear(); materialProperty.AddVector("_Color",Vector4(0,1,0,0.5)); Graphics.DrawMesh(aMesh, Vector3(5,0,0), Quaternion.identity, aMaterial, 0, null, 0, materialProperty);

// blue mesh materialProperty.Clear(); materialProperty.AddVector("_Color", Vector4(0,0,1,0.5)); Graphics.DrawMesh(aMesh, Vector3(-5,0,0), Quaternion.identity, aMaterial, 0, null, 0, materialProperty); }

Function variant that takes nameID is faster. If you are adding properties with the same name repeatedly, use Shader.PropertyToID to get unique identifier for the name, and pass the identifier to AddVector.

	// Draws 3 meshes with the same material but with different colors.
	// Using the material tag ID.

var aMesh : Mesh; var aMaterial : Material = new Material(Shader.Find("VertexLit"));

function Update() { var materialProperty : MaterialPropertyBlock = new MaterialPropertyBlock(); var tagID : int = Shader.PropertyToID("_Color");

// red mesh materialProperty.Clear(); materialProperty.AddVector(tagID,Vector4(1,0,0,0.5)); Graphics.DrawMesh(aMesh, Vector3(0,0,0), Quaternion.identity, aMaterial, 0, null, 0, materialProperty);

// green mesh materialProperty.Clear(); materialProperty.AddVector(tagID,Vector4(0,1,0,0.5)); Graphics.DrawMesh(aMesh, Vector3(5,0,0), Quaternion.identity, aMaterial, 0, null, 0, materialProperty);

// blue mesh materialProperty.Clear(); materialProperty.AddVector(tagID, Vector4(0,0,1,0.5)); Graphics.DrawMesh(aMesh, Vector3(-5,0,0), Quaternion.identity, aMaterial, 0, null, 0, materialProperty); }
