Ue5 small knowledge points geometry script modeling

append mesh With a problem ,mesh Will change occasionally normal Changed

use Boolean union Mode is OK It's just a little slow

---------------------------------------------------------------

ADynamicMeshActor It comes with a pool

UDynamicMeshPool* ADynamicMeshActor::GetComputeMeshPool()
{
	if (DynamicMeshPool == nullptr && bEnableComputeMeshPool)
	{
		DynamicMeshPool = NewObject<UDynamicMeshPool>();
	}
	return DynamicMeshPool;
}


UDynamicMesh* ADynamicMeshActor::AllocateComputeMesh()
{
	if (bEnableComputeMeshPool)
	{
		UDynamicMeshPool* UsePool = GetComputeMeshPool();
		if (UsePool)
		{
			return UsePool->RequestMesh();
		}
	}

	// if we could not return a pool mesh, allocate a new mesh that isn't owned by the pool
	return NewObject<UDynamicMesh>(this);
}
