#include <ComposableCameraOcclusionFadeNode.h>Per-primitive record of materials replaced while the primitive is in the faded set. Stored as a USTRUCT on the node so GC keeps the original-materials array alive until we restore it, which avoids a dangling-pointer risk the moment a mesh's only remaining reference to its original material is this record.
OverrideMaterials is kept in lockstep with OriginalMaterials for symmetry and debug inspection — it also pins the MID we created from the user's OcclusionMaterial, so that reloading / hot-reloading the source material doesn't immediately invalidate our swap.
Public Attributes¶
| Return | Name | Description |
|---|---|---|
TWeakObjectPtr< UPrimitiveComponent > |
Component |
The primitive whose material slots we swapped. Weak ref so actor destruction (e.g. NPC pooled away) cleans itself up — we prune stale entries each tick. |
TArray< TObjectPtr< UMaterialInterface > > |
OriginalMaterials |
Original UMaterialInterface per element index, captured at swap time. |
TArray< TObjectPtr< UMaterialInterface > > |
OverrideMaterials |
MIDs we created from the occlusion material per element index. Recorded so the node holds a hard GC reference to them for the lifetime of the override. |
