| index | The LOD level to use. Passing a negative index value enables automatic LOD selection. |
Disable automatic LOD selection based on camera distance by forcing a specific LOD level, or revert to the default automatic behavior by passing a negative value as parameter.
This method specifies explicitly which LOD level Unity should use. You can achieve the same result in a script by disabling the LODGroup component and renderers of the unneeded LOD levels, but using the ForceLOD method provides slightly better CPU performance. This is relevant if you need to force a particular LOD state only for a few frames. This method lets you avoid storing the original states of the renderers when you force an LOD level.
If you need to force a particular LOD level for a large number of LODGroups for a large number of frames, the alternative approach of disabling the LODGroup and renderers might provide better CPU performance.
using UnityEngine;
public class SampleScript : MonoBehaviour { public bool isHero = false;
private LODGroup m_LODGroup;
void Start() { m_LODGroup = GetComponent<LODGroup>(); }
void Update() { if (!m_LODGroup) return;
// Force LOD to highest quality level (0) when in hero mode // Else enable automatic LOD selection (-1). m_LODGroup.ForceLOD(isHero ? 0 : -1); } }
