Different objects use the same material and have different performances

Knowledge point

Material property block MaterialPropertyBlock
Set material block color attributes MaterialPropertyBlock.SetColor
Copy a material's attribute block Renderer.GetPropertyBlock
Set material attribute blocks Renderer.SetPropertyBlock

Realization

1. Through the model Render Get material block ;
2. Set the color attribute of the material block ;
3. Set up Render Material block for .

using UnityEngine;
public class NotSameDisplay : MonoBehaviour
{
    
    Renderer render;
    void Start()
    {
    
        render = GetComponent<Renderer>();
        ChangeMaterilaColor();
    }
    void ChangeMaterilaColor()
    {
    
        MaterialPropertyBlock newBlock = new MaterialPropertyBlock();
        //render The material values of are copied to newBlock in 
        render.GetPropertyBlock(newBlock);
        // Parameter one ：shader Corresponding property name in 
        // Select material   Click on the gear in the upper right corner   choice Edit Shader  stay Properties Block to view 
        // Parameter two ： The value of the property 
        newBlock.SetColor("_Color",Color.red);
        // Copy the new value into the attribute 
        render.SetPropertyBlock(newBlock);
    }
}
