MAG Prop Placer Pro - Fast Prefab Painter

MAG Prop Placer PRO is a production-ready Unity Editor tool designed to drastically speed up level design and environment creation, while keeping full control, safety and performance in mind.

It allows you to place prefabs using single placement, brush painting, or multi-object area stamping, with real-time scene preview, strict placement rules and optional renderer overrides.

The tool is built to work reliably in large scenes, open worlds, and especially mobile and low-end mobile projects, where performance and consistency are critical.

Core Placement Modes

• Place Mode – precise single-click placement using surface raycasts
• Brush Mode – paint prefabs while dragging, with minimum distance control to prevent overlaps
• Multi-Object (Area) Mode – place multiple prefabs randomly inside a radius, with density control and safe spacing
• Eraser Mode – remove only tool-placed objects using a configurable radius (safe deletion)

Professional Placement Control

• Real-scale ghost preview (no flickering)
• Align to surface normal with slope limits
• Random or fixed rotation (yaw)
• Random or fixed scale
• Grid snapping for modular level design
• Surface offset to avoid z-fighting
• Optional collider auto-add for prefabs without colliders

Avoid Layers & Safety

• Fully enforced Avoid Layers system
• Placement is blocked in Place, Brush and Area modes if avoid layers are detected
• Prevents accidental placement on roads, buildings, water or protected geometry
• Optional marker component to safely identify tool-placed objects

Smart Organization & Workflow

• Profile-based system using Prop Palette assets
• Unlimited categories per profile
• Fast search (category or global)
• Pagination for large prefab libraries
• Select All / Deselect All for quick batch operations
• Duplicate scanner and auto-fix for clean palettes
• Replace Tool for swapping scene objects while keeping transforms

Mobile & Performance Friendly

• Optional Force Renderer Settings (Cast Shadows / Receive Shadows)
• Applied only when enabled, otherwise original prefab settings are preserved
• Designed to reduce draw cost and shadow overhead on low-end devices
• Ideal for mobile, open-world and optimization-focused projects

Profiles & Data Safety

• JSON import/export for profiles (backup & sharing)
• Non-destructive workflow (never deletes prefab assets)
• Safe erase mode only affects objects placed by the tool

MAG Prop Placer PRO is built for indie developers, solo creators, and studios who want fast iteration, clean scenes and predictable results — without sacrificing performance or control.
