SPAWN MORE. OPTIMIZE MORE. SHIP SMOOTHER.

Two complete Unreal Engine systems for wave-based, horde and NPC-heavy games – built for single-player, multiplayer and dedicated servers.

Create enemy waves quickly, then automatically reduce the runtime cost of large NPC crowds.

Every included product is the same full version as its individual Fab listing, including updates and documentation.

WHAT'S INCLUDED

1. FULLY CUSTOMIZABLE ENEMY SPAWN SYSTEM

Build complete wave-based enemy spawning in minutes.

A Blueprint-only, network-replicated spawning system for single-player and multiplayer games.

Features

• Unlimited independent spawn zones
• Box and sphere spawn areas
• Spawn around players or across the world
• Configurable minimum and maximum spawn distance
• Limited or unlimited waves
• Enemies per wave and wave delays
• Maximum simultaneous enemy limits
• Enemy scaling based on player count
• Progressive health and speed scaling
• Boss spawning by kills or wave number
• Defense mode for players or objectives
• Simple AI included for testing
• Easily replace the included AI with your own
• 10 clean and organized Blueprints

Ideal for horde modes, survival games, co-op shooters, arena games, tower defense and wave-based gameplay.

2. NPC OPTIMIZER PRO

Keep large NPC crowds under control.

Add one component to a Pawn or Character and NPC Optimizer Pro automatically assigns NPCs to optimization tiers based on distance or significance.

Different tiers can reduce the cost of:

• Animation update rate
• Bone refresh
• Actor Tick
• CharacterMovement
• AI updates
• Network update frequency

Nearby and gameplay-critical NPCs can remain highly responsive while distant NPCs update less often.

Multiplayer & Dedicated Server Ready

Designed with gameplay correctness in mind.

Important gameplay events such as:

• Root-motion montages
• Gameplay montages
• Critical animation notifies
• Nearby combat

can remain accurate across clients, listen servers and dedicated servers.

Built-In Presets

Includes four ready-to-use optimization presets, including:

Horde – tighter tiering for large wave-based enemy groups
Dedicated-Server Shooter – designed for networked NPC-heavy games

MEASURE THE RESULT

NPC Optimizer Pro includes a live runtime dashboard so you can see where your NPC budget is going.

• Server and client world selection in multiplayer PIE
• Live optimization information
• Built-in A/B performance capture
• Compare baseline vs optimized performance in the same session
• Median and p95 Actor Tick measurements
• Server bandwidth measurements
• Export results to CSV or JSON

Optimize with measurable data instead of guesswork.

SAFE BY DEFAULT

NPC Optimizer Pro snapshots the values it changes and avoids overwriting values modified by your own gameplay code.

Optimization can be disabled instantly through:

npo.Enabled

or through individual optimization switches.

Original NPC settings can be restored automatically.

BUILT TO WORK TOGETHER

1. Spawn your enemies

Place spawn zones and configure waves, bosses, difficulty and enemy limits.

2. Optimize your NPCs

Add the NPC Optimizer component to your enemy Pawn or Character and select the Horde preset.

3. Press Play

Nearby enemies remain responsive while distant enemies can update less frequently.

4. Measure the result

Use the live dashboard and built-in A/B capture to verify the performance difference.

Both systems remain completely independent, so you can use them together or separately.
