How to change NPC template (TPLT) ?

[pxd2050]

I am creating a skse dll to change the npc Template(LPLT) and Template Flags(Use Traits) and have encountered some problems seeking help.

I have changed the Template and Flags of NPC, but it don't work in the game(npc1 -> npc2). May I ask where the problem ?

void MessageHandler(SKSE::MessagingInterface::Message* a_message)

{

	switch (a_message->type) {

		case SKSE::MessagingInterface::kDataLoaded:

			{

				if (INI::GetConfigs_NPCReplacer()) {

					logger::info("{:*^50}", "NPCReplacer");

					NPCReplacer::force_NPCReplacer();

				}

			}

			break;

		default:

			break;

	}

}

..........

void force_NPCReplacer()

	{

		for (auto& data : INI::configs_NPCReplacer) {



			for (auto npc1 : data.npcs1) {

				int  i = std::rand() % (data.npcs2.size());

				auto npc2 = data.npcs2[i];

				npc1->baseTemplateForm = npc2;

				npc1->actorData.templateUseFlags.set(RE::ACTOR_BASE_DATA::TEMPLATE_USE_FLAG::kTraits);



				logger::info("{}  ->  {}", npc1->GetFormID(), npc2->GetFormID());

			}

		}

	}
