lod-occlusion-culling

To set up LOD groups for 3D props in Unity, use this skill to configure Level of Detail hierarchies that automatically switch mesh complexities based on camera distance. This dynamically manages polygon counts to optimize rendering performance.

Occlusion culling is a rendering optimization technique that prevents the GPU from processing objects hidden behind other geometry. You need it in dense 3D environments, like open-world games, to significantly reduce draw calls and boost frame rates.

Yes, occlusion culling works alongside frustum culling and distance-based LOD selection. The skill manages these culling hierarchies together to comprehensively reduce draw calls and polygon counts for distant or occluded objects.

The best way to reduce GPU load for distant objects in an open-world game is implementing Level of Detail and Occlusion Culling. This ensures distant assets render with fewer polygons and hidden objects are skipped entirely.

Your Unity environment likely has low frame rates because the GPU is overwhelmed by high polygon counts and unnecessary draw calls. Implementing LOD groups and occlusion culling reduces this load by skipping hidden objects and simplifying distant meshes.
