Unreal Engine 5’s Features: 


Unreal Engine 5’s special feature, Lumen, is like a magic spell that makes game lighting look super realistic. It’s awesome, but it also makes the game need more memory and power.

Size Trade-off:

Good Things:

  • Saves computer space and time by not needing to store pre-made lightmaps.

Not-So-Good Things:

  • Uses more computer memory (RAM) and needs a stronger graphics card (GPU), which might mean needing a better computer.


Nanite is another cool thing in Unreal Engine 5. It lets you add really detailed things to your game without making your computer slow down. It’s like magic for big, fancy shapes.

Size Impact:

Good Things:

  • Makes big, detailed things take up less computer space.

Not-So-Good Things:

  • Makes your computer work more to show the details in real-time.

World Partition:

World Partition is all about handling really big game worlds. It cuts them into smaller pieces that the game loads only when needed. It’s like reading a book where you only turn to the page you’re reading.

Size Implications:

Good Things:

  • Helps make huge game worlds without using too much computer memory.

Not-So-Good Things:

  • Makes game design a bit more complicated and needs careful planning.

Remember, Size is Like Picking Your Outfit:

These features affect how much space your game takes up, but it depends on what kind of game you’re making. If it’s a small, straightforward game, you might not need all the fancy features. But if you’re dreaming big with a huge, open-world game, these features become super important.

Tips for Keeping Things Just Right:

  • Use Good Pictures Wisely:
    • Pick pictures that look good but don’t use too much space. It’s like choosing the right photos for a scrapbook.
  • Think About Faraway Things:
    • Make faraway things in your game look a bit simpler to save computer work.
  • Bake Your Lights (If You Can):
    • For things that don’t move, like buildings, you can make the lighting ahead of time to help your computer.
  • Plan Your Game Like a Puzzle:
    • If your game is huge, think about how to load only the parts you need when you need them.

By understanding how these Unreal Engine 5 features affect the size of your game and using smart tricks, you can make amazing games without worrying too much about size problems. It’s all about finding the right balance between how awesome your game looks and how much space it takes up. Now, go ahead and conquer the Unreal Engine 5 world, clever game maker.

Mastering Unreal Engine 5:

Starting out with Unreal Engine 5 is exciting, but making sure your project isn’t too big can be a bit like taming a digital dragon. Don’t worry, fellow developer. I’ve got some tips and tricks to help you make your project run efficiently and stay nimble.

1. Picking the Right Stuff:


Don’t be tempted by super-detailed textures – they might look amazing up close but can make your project too big. Think about using texture atlases or smaller textures for things far away.


Even though Nanite is cool, it has limits. Take a look at your meshes and simplify them by removing unnecessary details. Remember, simpler meshes usually mean a smoother game.


Having lots of cool sounds is great, but too many can make things crowded. Keep the important sounds and music and consider removing background noises that don’t add much.

2. Baking Lights Can Help

Lumen’s real-time lighting is awesome, but it can use a lot of memory. For things that don’t move (like buildings), think about using pre-baked lighting. It helps keep your project looking good without overloading it. But be aware, pre-baked lighting doesn’t change like Lumen does.

3. Level of Detail (LOD):

LOD is like a superpower against making your project too big. Use it to simplify things that are far away, so your game runs smoothly. Distant trees don’t need all their tiny details.

4. Streaming Things Right:

World Partition lets you have big game worlds, but you need to be smart about loading things at the right time. Imagine serving a buffet – you don’t need to bring out all the food at once. Plan when things should show up in your game.

5. Checking and Changing:

Unreal Engine 5 has tools to help you see what’s making your game slow. Use them to find problems and make things work better. Don’t be afraid to try different settings – every little bit you save is a win.

Bonus Tip: Ask for Help.

The Unreal Engine community is full of people who know a lot. If you’re stuck or need advice, don’t hesitate to ask them. Together, we can make sure your game looks awesome without being too big.

By following these tips and being smart about making your project just right, you can make fantastic games with Unreal Engine 5. Now, go ahead and make your game awesome, brave developer. The world is waiting for your incredible creations.
