The Car Prep Tool is an add-on designed to streamline the process of preparing vehicle models for export to Unreal Engine 5. It automates common pipeline tasks such as pivot correction, world origin alignment, and auto-orientation to the +X axis to match Unreal Engine's forward vector. The tool also grounds the vehicle at Z=0 for immediate physics compatibility, applies all transforms, and dissolves complex parent hierarchies.

In addition to transform cleanup, the add-on analyzes physical dimensions and ensures a correct 1:1 scale. It provides an automated collection management system that sorts components into standardized categories like wheels, body, glass, calipers, and interior parts. For export, it offers a smart FBX workflow that can either output collections as separate files or consolidate selected components into a single FBX, configuring properties like orientation, geometry, and smoothing automatically.
