GetRenderersFilteringResults(ReadOnlySpan<int>) is obsolete.

Error message

GetRenderersFilteringResults(ReadOnlySpan<int>) is obsolete. Use GetRenderersFilteringResults(ReadOnlySpan<EntityId>) instead.

What it means

EditorCameraUtils.GetRenderersFilteringResults(ReadOnlySpan<int>) is decorated with [Obsolete(..., true)] (error=true), so any use is a compile-time error. The method body also throws NotImplementedException defensively for runtime/reflective access. The API was replaced by the EntityId-based overload GetRenderersFilteringResults(ReadOnlySpan<EntityId>, Span<bool>) because renderer identifiers are now EntityIds, not raw ints.

Solutions

Switch to the EntityId overload: GetRenderersFilteringResults(ReadOnlySpan<EntityId>, Span<bool>).
Convert your int renderer IDs to EntityId values using the current conversion API before calling.
Remove all references to the int-based overload from your codebase.

Example fix

// before
EditorCameraUtils.GetRenderersFilteringResults(rendererIntIds, results);

// after
EditorCameraUtils.GetRenderersFilteringResults(rendererEntityIds, results);

Defensive patterns

Strategy: type-guard

Validate before calling

// Ensure compile-time switch to the EntityId overload; remove all int-overload references.

Type guard

static void Call(ReadOnlySpan<EntityId> ids, Span<bool> results) => EditorCameraUtils.GetRenderersFilteringResults(ids, results);

Prevention

Migrate all calls to the EntityId overload.
Update tooling/packages that still use the int API.
Treat obsolete-with-error attributes as compile blockers, not warnings.

When it happens

Trigger: Calling GetRenderersFilteringResults with ReadOnlySpan<int> renderer IDs — either directly or via code that was not migrated. The obsolete marker makes this a hard error at compile time.

Common situations: Upgrading Unity versions where renderer IDs changed from int to EntityId; code targeting an older API surface; reflection/dynamic invocation that bypasses the compiler error.
