How to slowly change an objects transparency

I want to have an image of my company logo appear when I start the program, and I want to slowly fade to back and then have it load a new scene, does anyone know how to slowly change the transparency of and object?

I think the best solution to your problem is Splash Screen.

You can use a SceneManager.LoadSceneAsync with an animation between the scenes.

This would be the most simple way to do it

Create a C# script, name it ‘FadeOut’ and then drag it on your logo gameObject. Then copy/paste the code and tweak it.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class FadeOut : MonoBehaviour
{
    [Header("Fade Out Script")]
    public Image logoImage;
    [Tooltip("Will start the fade out after value (in seconds)")]
    public float timeToStartFading = 2f;
    [Tooltip("Higher values = faster Fade Out")]
    public float fadeSpeed = 1f;
    [Tooltip("Scene to Load (Must be stored in Builded Scenes Index -> File/Build Settings...)")]
    public int sceneToLoad = 1;

    public void Start()
    {
        //If you didn't drag the component
        if (logoImage == null)
            logoImage = GetComponent<Image>();
    }

    public void Update()
    {
        //Timer
        if (timeToStartFading > 0)
        {
            timeToStartFading -= Time.deltaTime;
            return;
        }

        //Modify the color by changing alpha value
        logoImage.color = new Color(logoImage.color.r, logoImage.color.g, logoImage.color.b, logoImage.color.a - (fadeSpeed * Time.deltaTime));
        
        //Basic scene change
        if (logoImage.color.a <= 0)
            SceneManager.LoadScene(sceneToLoad, LoadSceneMode.Single);
    }
}
