Get collision vertices?

Hi there,
I’m trying to return a vector array that will contain the positions of all the vertices from a static mesh’s collision mesh.

Is this possible? Here is what I have so far…

bool UMyFunctionLibrary::GetCollisionVertices(UStaticMeshComponent* Target, TArray<FVector>& VertexArray)
{
	if (!Target || !Target->IsValidLowLevelFast() || !Target->StaticMesh || !Target->StaticMesh->HasValidRenderData())
	{
		return false;
	}

	if (!Target->StaticMesh->ContainsPhysicsTriMeshData(true))
	{
		return false;
	}

	FTriMeshCollisionData CollisionData;
	Target->StaticMesh->GetPhysicsTriMeshData(&CollisionData, true);

	VertexArray = CollisionData.Vertices;
	return true;
}

But for some reason this returns the actual mesh’s vertices instead of the collision box.

Any tips?

For anyone looking for the same thing in the future: try looking UStaticMeshComponent::GetStaticMesh()->NavCollision->GetConvexCollision(). Data presense may depend on collision settings.
