A Blender Material Pack with reactive forcefields for Blender

Create dynamic, animated sci-fi shields that react to proximity, impacts, and openings. Entirely procedural.

✔ 12 procedural barrier materials + 5 modular layers
✔ animation controlled with simple Shape Keys
✔ proximity-based interaction
✔ animated openings & impacts
✔ Geometry Nodes proximity system included

Works on simple planes / domes, no simulations or textures required.

What you can create

Create dynamic shields such as:

• spaceship forcefields

• sci-fi base barriers

• cinematic shield impacts

• reactive energy walls

• holographic forcefields

Perfect for VFX shots, sci-fi scenes, environments, and animations.

Modular System : Asset Browser Workflow

The pack is built around a modular system that lets you extend the barriers using Blender’s Asset Browser.

Interaction layers such as impacts or proximity effects can be added directly by drag & drop.

This makes it easy to build complex reactive shields without modifying the base material.

How it works

1. Apply a barrier material to your surface.

2. Add the Geometry Nodes proximity controller to the barrier object (adjust the resolution/subdivisions).

3. Drag additional interaction layers from the Asset Browser.

Available layers include:

• 2 proximity interaction layers

• Multiple impacts layer

• 2 opening layers

Each layer automatically integrates into the barrier system.

Non-destructive workflow

The system is designed to stay modular and non-destructive.

You can:

• add multiple interaction layers

• combine effects together

• enable or disable layers at any time

This allows you to quickly experiment and build complex barrier behaviours.

Designed for flexibility

Because the layers are assets, you can easily:

• reuse them across scenes

• stack multiple effects

• customize them independently

The system keeps the barrier setup clean, flexible, and scalable.

Key Features

6 base barrier materials + 6 additional variations, all animated using Shape Keys

Six ready-to-use barrier styles, fully procedural and easily customizable.

Adjust:

• Light emission

• Cell width

• animation speed

• colors

No textures needed / UV unwrap required.

Radial Proximity System

Two proximity layers allow the shield to react to nearby objects. ("Proximity GN" geometry Nodes modifier required)

When geometry approaches the barrier, the material can locally:

• increase emission

• generate interaction glow

• Animated using Shape Keys

Powered by Geometry Nodes proximity detection.

Opening System

Create dynamic openings in the shield and control them using a simple empty.

Two styles included:

Electrical opening
Unstable arcs and energetic distortions.

Incandescent opening
Smooth glowing aperture for controlled passages.

Perfect for ships passing through shields or shield gates.

Multi-Impact System

Simulate multiple simultaneous impacts.

Each impact creates:

• local energy bursts

• animated glow pulses

• The shield reacts to impacts

Ideal for scenes with multiple projectiles shots.

Geometry Nodes Controller

The pack includes a Geometry Nodes proximity controller in order to use the radial proximity layers.

It detects nearby geometry and feeds interaction data to the materials.

This allows the barriers to react dynamically without simulations or dynamic paint.

The system remains lightweight and fully procedural.

In brief, what’s Included

• 12 procedural barrier materials

• 2 radial proximity layers

• 2 opening layers (electrical & incandescent)

• multi-impact system

• Geometry Nodes proximity controller

• customizable parameters

Easy to Use

1. Add the barrier material to a plane or surface (UV unwrap needed)

2. Optionnaly place the Geometry Nodes controller if you want to use a proximity layer ➜ Assign the collection with proximity objects ➜ Adjust the resolution (subdivision)

3. Add a layer in the shader editor

4. Adjust your parameters

5. Animate with shape keys if you want

The system is designed to stay simple and flexible
