how to do the nullscapes fade effect gd

Here’s the basic way the Nullscapes-style fade is usually done in Geometry Dash: build a black cover object, fade it in with an alpha trigger, switch the scenery during the blackout, then fade back out. The key is to make the change happen while the screen is fully dark so the transition feels smooth.

Setup

1. Make a large black object or block layer that covers the screen.
2. Give it a group ID.
3. Set its opacity to 0 at the start with an alpha trigger.
4. Use another alpha trigger to fade it to full black when the transition begins.

During the fade

• Put the old section on one group and the next section on another.
• Turn off the old group right as the screen reaches black.
• Turn on the new group while the screen is still black.
• Keep the fade timing short enough that the player doesn’t notice the swap.

Smoothness tips

• Use a black background too, if the level style allows it, so the fade blends better.

• Don’t rely on teleport portals for this effect if you want a cleaner cinematic transition.

• If the level has a visible floor, you may need to fade that as well so the seam doesn’t show.

Simple example

A common version looks like this:

1. Fade black overlay in.
2. Hide the first room.
3. Show the next room.
4. Fade black overlay out.

That’s basically the Nullscapes look: a blackout cut that hides the change and makes the level feel like it morphs instead of switching abruptly.

TL;DR

Use an alpha trigger on a black overlay, swap groups while the screen is fully black, then fade out again.
