This Blend file has been rebuilt using Blender version 3.0 to address crashing issues found in versions prior to 3.6.1. In this update, I attempted to resolve shading issues; however, it appears the problem lies with Blender itself. As a result, you’ll need to manually enable Auto Smooth for the normals on each mesh. I apologize for the inconvenience. Additionally, I’ve corrected the missing ambient occlusion on one of the meshes. High-poly meshes were removed to reduce the file size and ensure compatibility with earlier Blender versions. While this might seem counterintuitive, directly copying and pasting the models caused crashes in older Blender versions, making this change necessary.
