UCharacterMovementComponent::NavMeshProjectionInterval

property Engine Blueprint Since 4.0

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: UPROPERTYEditAnywhereBlueprintReadWrite

Description

Sets how often, in seconds, NavWalking characters raycast from the nav mesh down to the underlying geometry to keep their visual position matched to the floor.

Caveats & Gotchas

• Only has an effect when bProjectNavMeshWalking is enabled — it is ignored for ordinary walking movement.
• Lower values give a tighter visual match to uneven or moving geometry but cost more raycasts per second across all NavWalking characters.
• Setting this too high can cause visible popping when the character crosses geometry that diverges from the flat nav mesh surface.

Signature

float NavMeshProjectionInterval;

Example

Tighten navmesh projection for uneven terrain C++

void AMyAICharacter::PostInitializeComponents()
{
	Super::PostInitializeComponents();

	if (UCharacterMovementComponent* MoveComp = GetCharacterMovement())
	{
		MoveComp->NavMeshProjectionInterval = 0.1f;
	}
}
