Key features:

Customizable Grid System

Define grid cell sizes and use custom prefabs or the included grid shader for visual grid representations to match your game's unique style.

Smart Object Adaptation & Pivot Centering

• Automatic Size Calculation: No manual math required! OmniGrid uses Scriptable Objects and custom editor scripts to automatically pre-calculate object boundaries.
• Pivot Alignment: Misaligned 3D model pivots? Simply assign the included CenterMeshXZ script to your model holder to ensure perfect grid alignment and rotation effortlessly.
• Dynamic Object Size: Avoid unwanted gaps when using fixed-size terrain objects across different cell sizes. Toggle the dynamicSize flag to let the object scale dynamically to the cell.

Multi-Layered Placement

Utilize multiple GridData levels, allowing completely different object types (e.g., terrain, buildings, decorations) to independently occupy the exact same coordinate position.

Dynamic Object Rotation

Rotate buildings at specified angles for more dynamic, organic, and creative placement styles.

Integrated Save System

Automatically saves your grid data on exit and reloads the scene state on game start, ensuring persistent worlds without extra setup.

UI & Configuration Modules

• Tab-Based Shop UI: Clean, intuitive UI layout to quickly categorize and select different placeable object types.
• Smart Remove UI: Delete objects with precision filtering (e.g., remove only decorations while leaving buildings intact). Alternatively, hold the mouse over an object to quickly choose between move and delete actions.
• Global Game Configurator: Manage all essential asset and placement configurations from a single centralized panel.
