How to export FBX 3D models for VR?

To export FBX 3D models for VR, optimize the model (reduce polygons, fix topology) then use your 3D software’s export to select FBX and adjust settings—embed textures and match your VR platform’s coordinate system (e.g., Unity Y-up, Unreal Z-up). Optimization is critical for VR performance—too many polygons cause lag. Embedding textures ensures consistent visuals, and correct coordinates prevent misalignment in VR. For new users, test a simple model (like a chair) in Unity first. This helps spot issues (e.g., missing textures) early without complex assets slowing you down.
