how to preload assets with progress bar

I know about preloaded assets in play settings. But I want it with progress bar.

The problem is I dont have a option to show a progress bar while assets are loading. I want to make a loading scene which will be the first scene of the game. And in that scene I will load all assests which will be needed all the time & while loading those assets need to show a loading bar with progress.

Anybody have a solution for this?

 

Isn't AssetBundle for DLC?? I mean if I load an assetbundle, will it remain in the RAM/VRAM all the time??
I actually want the feature of "Preloaded Assets" in PlayerSettings.

 

Not what I was looking for actually. Right now everything referenced to the scene itself. No manuall stuff. If I use asset bundle I have to manually handle the references.

The thing is I have a big scene and loading it takes time. Whenever I come from another scene to that big scene it takes time.

Now I want to make all the sprites of that big scene loaded at the game startup & remain loaded in VRAM. So that when that scene again loads it doesn't need to load all the sprites again.

NOTE: I'm not doing any Resource.Load. Everything referenced to the scene itself.

I have done it by "Preloaded Assets" option in PlayerSettings. But when I'm using it taking time on the black screen before the first scene.. Thats why I want to manually do the thing which "Preloaded Assets" options does & show a progress bar.

Any Help?
