Shader.isSupported

Description

Can this shader run on the end-users graphics card? (Read Only)

Returns true if the shader itself or any fallbacks setup in the shader are supported. Most often you use this when implementing special effects.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Disable renderer if material's shader is not supported
        Renderer rend = GetComponent<Renderer>();

        if (!rend.material.shader.isSupported)
        {
            rend.enabled = false;
        }
    }
}
