FlexiArray Pro is an add-on that provides tools for object replacement and procedural array generation. The replacement feature allows users to swap objects within a scene while maintaining their original transformations. The array system generates randomized object distributions using either individual assets or entire collections. Users can control array parameters including radius, rotation, and positional offsets. The add-on includes an automated protection against duplicate objects during array generation and provides a reset function to quickly clear a setup. It is designed to simplify asset placement and layout tasks.
