1. Use Occlusion Culling: Occlusion culling is a technique used to optimize the performance of a VR or AR experience by eliminating any objects that are outside of the user’s view. This can be done in Unreal Engine by using the Occlusion Culling system which will automatically detect and remove any objects that are out of view.
2. Use Level-of-Detail (LOD) System: The LOD system is a technique used to optimize the performance of a VR or AR experience by reducing the level of detail of objects depending on the distance from the user. This can be done in Unreal Engine by using the LOD system which will automatically reduce the level of detail of objects depending on the distance from the user.
3. Use Lightmaps: Lightmaps are a technique used to optimize the performance of a VR or AR experience by precalculating the lighting of static objects. This can be done in Unreal Engine by using the Lightmass system which will automatically calculate the lighting of static objects and save them to a lightmap.
4. Use Post-Process Effects: Post-process effects are a technique used to optimize the performance of a VR or AR experience by applying graphical effects to the rendered image. This can be done in Unreal Engine by using the Post-Process Volume system which will allow you to apply various graphical effects to the rendered image.
