nameID プロパティー名 ID。Shader.PropertyToID を使って取得します。
name プロパティー名。例えば、"_MainTex"。
value 設定するテクスチャ
element Optional parameter that specifies the type of data to set from the RenderTexture.


Sets a named texture.

多くのシェーダーでは複数のテクスチャを使用します。テクスチャを変更するには SetTexture を使用します (シェーダーの propertynName、または、プロパティー固有の nameID から識別)。

標準シェーダーを使用しているマテリアルのテクスチャを設定するとき、以前使用していないシェーダーの機能を有効にするために EnableKeyword を使用する必要があることに注意しなければなりません。詳細については Accessing Materials via Script を参照してください。

Common texture names used by Unity's builtin shaders:
"_MainTex" is the main diffuse texture. This can also be accessed via mainTexture property.
"_BumpMap" is the normal map.

The shader properties also show some of the keywords needed to set the Texture of a Material. To see this, go to your Material and right click on the Shader dropdown at the top. Next, pick Select Shader.

By specifying a `RenderTextureSubElement`, you can indicate which type of data to set from the RenderTexture. The possible options are: RenderTextureSubElement.Color, RenderTextureSubElement.Depth, and RenderTextureSubElement.Stencil.

//Attach this script to your GameObject (make sure it has a Renderer component)
//Click on the GameObject. Attach your own Textures in the GameObject’s Inspector.

//This script takes your GameObject’s material and changes its Normal Map, Albedo, and Metallic properties to the Textures you attach in the GameObject’s Inspector. This happens when you enter Play Mode

using UnityEngine;

public class Example : MonoBehaviour {

//Set these Textures in the Inspector public Texture m_MainTexture, m_Normal, m_Metal; Renderer m_Renderer;

// Use this for initialization void Start () { //Fetch the Renderer from the GameObject m_Renderer = GetComponent<Renderer> ();

//Make sure to enable the Keywords m_Renderer.material.EnableKeyword ("_NORMALMAP"); m_Renderer.material.EnableKeyword ("_METALLICGLOSSMAP");

//Set the Texture you assign in the Inspector as the main texture (Or Albedo) m_Renderer.material.SetTexture("_MainTex", m_MainTexture); //Set the Normal map using the Texture you assign in the Inspector m_Renderer.material.SetTexture("_BumpMap", m_Normal); //Set the Metallic Texture as a Texture you assign in the Inspector m_Renderer.material.SetTexture ("_MetallicGlossMap", m_Metal); } }
