Introduction

Welcome to this tutorial on using the new Embryo Engine 5's procedural generation plugin. In this tutorial, we will be exploring the features of the 5.2 version of the plugin and how to use it to Create stunning environments. We will be using the Rainforest Pack as an example to showcase the capabilities of the plugin. So, let's dive in and get started!

Installing the Procedural Generation Plugin

To begin using the Procedural Content Generation Framework plugin, You need to install it in your Unreal Engine 5 project. To do this, follow these steps:

1. Open your project in Unreal Engine 5.
2. Go to the "Edit" menu and click on "Plugins".
3. In the plugins window, search for "Procedural Content Generation Framework" and enable it.
4. A pop-up will appear, asking you to restart the editor. Click on "Restart Editor" to enable the plugin.
5. Once the editor restarts, the plugin will be enabled and ready to use.

Creating a New Level

Before we start using the plugin, let's create a new level in our project. Creating a new level will allow us to showcase how the procedural generation works in an open world setting.

To create a new level, follow these steps:

1. Open the Unreal Engine Editor.
2. Go to the "File" menu and click on "New Level".
3. Select the "Open World" template for our new level.

Once the new level is created, we can proceed to use the procedural generation plugin.

Using the PCG Volume

Now that we have our new level ready, let's start using the Procedural Content Generation (PCG) Volume to generate our environment. The PCG Volume is a component that defines the area in which we want to generate our content.

To use the PCG Volume, follow these steps:

1. In the level editor, click on the "Add" button in the toolbar.
2. Search for "PCG Volume" and drag it into the scene.
3. The PCG Volume will appear as a square Shape in the scene.
4. Adjust the size of the PCG Volume to define the area where you want to generate your content.

The PCG Volume will be the area in which our generated content, such as trees and bushes, will be spawned.

Creating a PCG Graph

Now that we have our PCG Volume in place, let's create a PCG Graph. The PCG Graph is where we define the rules and logic for generating our content within the PCG Volume.

To create a PCG Graph, follow these steps:

1. Select the PCG Volume in the scene.
2. In the PCG Volume's component details panel, click on the "Graph" dropdown and select "Create New Asset".
3. Give the PCG Graph a name and click on "Save".

The PCG Graph will appear as a graph editor, similar to other Unreal Engine visual scripting systems such as Blueprints. We will be using this graph to define the rules for generating our content.

Adding Surface Sampling

To begin generating content within our PCG Graph, we need to add a Surface Sampler node. The Surface Sampler node allows us to sample the landscape or terrain within the PCG Volume and generate content Based on that.

To add a Surface Sampler node, follow these steps:

1. Right-click in the PCG Graph editor.
2. Search for and select the "Surface Sampler" node.
3. Connect the output of the Surface Sampler node to the output of the PCG Graph.

The Surface Sampler node will randomly pick points on the surface within the PCG Volume and spawn content based on those points.

Spawning Static Meshes

Now that we have our Surface Sampler set up, let's add a Static Mesh Spawner node to spawn static meshes in our scene. The Static Mesh Spawner node allows us to spawn static meshes at the sampled locations from the Surface Sampler.

To add a Static Mesh Spawner node, follow these steps:

1. Right-click in the PCG Graph editor.
2. Search for and select the "Static Mesh Spawner" node.
3. Connect the output of the Surface Sampler node to the input of the Static Mesh Spawner node.
4. Configure the Static Mesh Spawner node by selecting the mesh you want to spawn.

The Static Mesh Spawner node will spawn the selected mesh at the sampled locations on the surface within the PCG Volume.

Adjusting Density and Scale

To fine-tune the density and scale of our generated content, we can adjust the parameters of the Surface Sampler and Static Mesh Spawner nodes.

To adjust the density, follow these steps:

1. Select the Surface Sampler node in the PCG Graph editor.
2. In the details panel, locate the "Points Per Square Meter" parameter.
3. Adjust the value to increase or decrease the density of the sampled points.

To adjust the scale of the static meshes, follow these steps:

1. Select the Static Mesh Spawner node in the PCG Graph editor.
2. In the details panel, locate the "Scale" parameter.
3. Adjust the value to increase or decrease the scale of the spawned static meshes.

Experiment with different density and scale values to achieve the desired result for your environment.

Adding Multiple Meshes

In our environment, we may want to add multiple types of static meshes. The Static Mesh Spawner node allows us to add multiple meshes and have them share the density across the different types.

To add multiple meshes, follow these steps:

1. Select the Static Mesh Spawner node in the PCG Graph editor.
2. In the details panel, locate the "Mesh Entries" parameter.
3. Click on the "+" button to add a new mesh entry.
4. Select the mesh you want to add for the new entry.

By adding multiple mesh entries, we can have different types of static meshes spawned in the environment while still maintaining the desired density.

Adding Ground Cover

To add ground cover, such as bushes and flowers, we can create another Surface Sampler and Static Mesh Spawner set and adjust the parameters to our liking.

To add ground cover, follow these steps:

1. Right-click in the PCG Graph editor.
2. Add another Surface Sampler node and connect it to the PCG Graph output.
3. Add another Static Mesh Spawner node and connect it to the output of the new Surface Sampler.
4. Adjust the parameters of the new Surface Sampler and Static Mesh Spawner nodes.
5. Select the meshes you want to use for the ground cover.

By creating separate sets of Surface Sampler and Static Mesh Spawner nodes, we can add additional layers of content, such as ground cover, while maintaining the density of each layer.

Enhancing the Scene with a Landscape Material

To add more Detail and visual appeal to our environment, we can Apply a landscape material to our landscape.

To enhance the scene with a landscape material, follow these steps:

1. Locate a suitable landscape material for your environment. In this example, we will use the materials from the Rainforest Pack.
2. Import the landscape material into your project.
3. Apply the landscape material to your landscape in the level editor.

By applying a landscape material, we can add textures and shaders to our landscape, making it look more realistic and visually appealing.

Final Touches and Optimization

To finalize our environment and optimize it for performance, we can make some final adjustments and optimizations.

Some final touches and optimizations could include:

• Adjusting lighting and post-processing effects.
• Adjusting the density and scale of the generated content.
• Adding additional detail, such as foliage and decals.
• Optimizing the materials and textures used in the environment.
• Testing the environment in different lighting conditions and gameplay scenarios.

By fine-tuning the details and optimizing the environment, we can create an immersive and visually stunning experience while maintaining good performance.
