Want your take your game to the limit?
Our Pro Physics World will elevate your game and save countless hours of development time – no coding required.
Lets jump right in and see the magic in action!

Foliage Physics

Our Pro foliage physics system intelligently detects nearby plants and seamlessly converts them into interactive blueprints using highly efficient object pooling methods.
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:

  • Performance Boost: Optimized for AAA games, the only bottleneck here is Unreal’s native physics engine! Our conversion system has 0% performance impact!
  • Auto-Variation: Say goodbye to identical plants! Create diverse ecosystems with plant materials that automatically change color, brightness, and saturation.
  • Animatable Variables:  bioluminescent jungles or alien fields that light up on touch!
  • Pro Explosions: We included an optimised explosive projectile to showcase how our physics system handles numerous explosive interactions!
  • 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.
  • Controlled Culling: Choose when the Foliage Influencer activates: always on, in view, within a certain distance, or both.

Pro Foliage Parent Blueprint

Our foliage parent blueprint got an huge upgrade! We’ve now opened the door to unlimited custom effects.
Plants now light up when you touch them, ballons pop when recieving damage, and much more!
We have exposed a range of events and variables allowing you to easily create and animate different effects.

Pro Grass & Mud Trails

Grass now reacts to distance field lighting, creating mesmerizing glow waves around rocks and plants.
As players and objects move through it, they trample the grass, triggering a bioluminescent glow.
If you find yourself caught in the rain, you’ll leave behind trails of mud, displacing the landscape as the waters rise.

Storm Level & Lightning Effects

This pack comes with not one level, but two! Enter the storm, as our advanced weather system fades in rain particles, fog, material wetness, and splashing effects.
It includes 2D background lightning and procedural 3D foreground lightning strikes, casting realistic parallaxed landscape shadows.
With user-friendly documentation, it’s designed for seamless integration into any environment.

Water Fluid Simulation

Using Unreal’s native water plugin, we’ve integrated fluid simulation for lifelike liquid movement.
The distance-field bioluminescent water material, featuring glowing player ripples, creates a stunning visual experience.
Additionally, we’ve included a Rising Water blueprint that uses runtime virtual textures for player ripples, offering a variety of dynamic options!

Pro Wind System

Transform your landscape with the Pro Etherion Wind System – with zero vertex stretching issues!
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.

Distance Field Improvement Hack

Ever noticed how Unreal 5 has super pixelated distance fields, while Unreal 4 didn’t?
This known issue has even been recognized by the devs at Epic Games. But don’t worry—we’ve hacked a fix!

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.
