Foliage Physics

Our advanced foliage physics system intelligently detects nearby plants and seamlessly converts them into interactive blueprints.
When the physics blueprint moves away from the plant, it converts back into a foliage instance – ensuring smooth performance.
We’ve integrated 6 plants into the system, ready to enhance your world with vibrant and interactive vegetation with the following features:

  • Scale-based Physics: Automatically adjust plant physics by size, whether you want them free-flowing, resistant, or rock solid.
  • Sound FX: Make your foliage play sound effects on collision. We’ve included 11 plant sounds and 9 balloon sounds you might find useful.
  • Adjustable Timing: Set the time it takes for your foliage to reset to its base-pose.
  • Explosions: We included an explosive projectile template to showcase how our physics system handles even the most explosive interactions!
  • Parent Blueprint: Each plant is based on a single blueprint, allowing easy modifications and quick creation of new foliage types.
  • Performance Culling: Choose when the Foliage Influencer activates: always on, in view, within a certain distance, or both.

Wind System

Transform your landscape with the Etherion Wind System.
This powerful tool blankets your entire level with a dynamic wind map, bringing each plant to life with realistic animations.
Customize wind intensity, speed, and scale to enhance the realism and immersion of your environment effortlessly.

Planets and Atmosphere

Experience realistic planet materials with varying ring sizes, vibrant nebulae, and twinkling star effects.
This package also includes two mountains and a range of efficient cloud materials, creating an immersive and visually captivating atmosphere.

Auto-Snow Materials

Discover our pack of 7 rocks featuring an auto-snow-surface material, ensuring snow stays on top for realistic transitions.
This adds a touch of authenticity and visual appeal to your environments, making them more immersive and lifelike.

Footstep Sound Effects

Automatically detect the surface beneath your player and play the right footstep sound.
There are 29 ground sounds like dirt, grass, mud, and sand, plus 16 water footstep sounds.

Extensive Documentation

The Alien Physics World includes extensive step-by-step documenatation and tutorial videos to help you set up and customize the system.
Whether you’re a beginner or an experienced developer, these tutorials will help you master the Foliage System quickly.


Note: This asset utilizes Skeletal Meshes and Physics assets, not Vertex Animation.
If you wish to create your own interactive foliage meshes, you must create Skeletal Meshes using 3rd Party Software.
