Unreal Engine 5: Constructing Worlds With Quixel Megascans

This text explores the Unreal Engine 5 panorama editor and how one can carry free, high-resolution Quixel Megascans into your mission to jumpstart your sport improvement.

It continues from the Unreal Engine 5 Tutorial for Freshmen that launched the essential ideas of working within the Unreal Engine 5 editor. In the event you aren’t already acquainted with the final interface and ideas, together with Blueprints and Actors, I like to recommend beginning there earlier than persevering with with this one.

After this tutorial, you’ll have a very good grasp on:

• Discovering high-quality Megascans property through the Quixel Bridge
• Working inside Unreal Engine’s built-in Panorama Editor
• Making use of all of the instruments accessible within the Panorama Editor to construct the world
• Implementing advanced blended textures through Blueprints
• Portray a number of textures on a panorama

Just like the newbie tutorial, the hero of this sport is a mighty submarine. Time to present this submarine a world to discover!

Notice: This tutorial makes use of Unreal Engine 5.2. Nonetheless, Epic Video games consistently updates Unreal Engine, so your model may be totally different than what’s proven within the photographs right here, and views may change because the engine evolves.

Getting Began

Obtain the starter mission by clicking Obtain supplies on the high or backside of the tutorial.

On this tutorial, you’ll use Unreal Engine 5’s Panorama editor and Quixel Megascans to create a wealthy panorama of underwater valleys in your submarine to navigate by. Within the course of, you’ll learn to add textures to surfaces, combine textures for a customized look and add premade property to your scene.

Understanding Quixel Megascans

Earlier than you begin, what precisely are Quixel Megascans?

Quixel is an organization that’s constructed the world’s largest 2D and 3D asset library derived from the strategy of photogrammetry: high-resolution picture scans of real-world objects and textures. In November of 2019, Epic Video games, maker of Unreal Engine, introduced the thrilling information that it had acquired Quixel and would make the whole asset library accessible to Unreal Engine customers. Unreal Engine 4.24 marked the start of an built-in workflow to carry Quixel property into Unreal Engine video games. Examples of objects and textures fantastically captured by photogrammetry and accessible through the Megascans library are proven under.

With the discharge of Unreal Engine 5, the combination of Quixel has improved additional. Now, it’s fairly seamless to go looking Quixel property within the Unreal Engine editor, then obtain and add these to your sport ranges. On this tutorial, you’ll begin with a primary introduction to the Unreal Engine 5 Panorama editor, and then you definately’ll use Quixel property to construct a extra advanced scene shortly.

Navigating the Unreal Engine 5 Panorama Editor

Start by opening the starter mission in Unreal Engine 5. You’ll see the essential mission view within the editor, and a World Partition tab must be open within the right-hand aspect panels.

If the World Partition isn’t open, open it with Window ▸ World Partition ▸ World Partition Editor. By default, when you haven’t beforehand loaded a streaming world asset, you’ll want to spotlight after which select to load a area into the editor to show landscapes and property at present within the map.

Panorama Mode

After you load the area, the scene continues to be empty apart from a post-process quantity that provides the world a bluish tint and an underwater environment. It’s time to construct a panorama! So, subsequent, you must activate Panorama mode to change editor views into the Unreal Engine 5 Panorama editor. Discover the Panorama choice from the dropdown menu within the UE5 toolbar, or use the Shift-2 hotkey to change to this view.

After Panorama mode prompts, a brand new panel of controls seems on the left-hand aspect of your editor window. After getting a Panorama, these Sculpt controls might be accessible.

However earlier than you should use them, you’ll must have a Panorama, both by creating one or importing current knowledge to be the idea of the Panorama. You’ll quick-start a Panorama on this mission by importing a pre-generated heightmap. Change to the Handle tab within the Panorama pane. You’ll create a brand new Panorama however use an current heightmap to hurry up the method.

Click on New+, after which:

1. Click on Import from File.
2. Browse to the offered world map known as ocean-trench-map.png included within the world-map folder within the starter downloads.
3. Select a Materials, and choose M_MS_Default_Material to offer a primary beginning texture to see in your panorama.
4. Use the default Total Decision of 2017 × 2017.
5. Click on Import to create the brand new panorama.

Utilizing the Scuplt Instruments

After the import, which creates a brand new Panorama, you’ll have a visual ocean trench you could edit with the instruments within the Sculpt menu.

The sculpting instruments work on the underlying heightmap of your panorama. As you’re employed with these instruments, the left mouse button performs the at present highlighted motion on the heightmap so as to add/elevate the terrain. The left mouse button-Shift performs the identical motion, however subtractively to decrease the terrain. Management-Z undoes the final stroke, and Management-Y redoes the final undone motion.

Sculpting Instruments

Right here’s what a few of these instruments do:

• Sculpt is the essential software to lift or decrease the heightmap utilizing the left mouse button or left mouse button-Shift.
  
• Erase removes heights from the heightmap shortly.
• Clean softens and smooths the heightmap. The Brush Energy impacts how shortly this occurs if you draw on the Panorama.
• Flatten takes the peak of the preliminary click on of the motion on the Panorama, and as you maintain and drag, the Landscapes rise or decrease to match that peak.
  
• Ramp lets you left-click and drag to mark a beginning and ending level for a ramp. After setting these positions within the Device Settings under the motion buttons, you’ll be able to Add Ramp to finalize and construct a sculpted ramp into the heightmap.
• Erosion simulates thermal erosion to maneuver soil from larger elevations to decrease ones by pure forces. This may create pure and random removals from the Panorama heightmap.
  
• Hydro or Hydro Erosion simulates hydraulic erosion, or water flows, to regulate the heightmap. This creates Landscapes the place eroded areas look as if rain has regularly affected the Landscapes over time.
• Noise lets you paint onto a Panorama floor with variations in heights.
• Retop or Retopologize instruments regulate the Panorama to enhance the vertex densities in areas which will require it, like very steep cliff edges. This will likely assist scale back artifacts like texture stretching.

Be happy to attempt all of the totally different sculpting instruments to change the undersea panorama. Don’t overlook to make use of left mouse button-Shift to use the inverse motion, usually to decrease the panorama.

With the panorama sculpted, now you can add textures to the floor.
