Good, I’ve got a notification this time, maybe the forums are improving.
Hello, you can spawn included presets using the Spawn Actor From Class, if you wish to do this in game. Then you can expose desired generation parameters via the Expose on Spawn variable checkbox. So getting a socket location and feeding it into the spawn transform should work, but every spawned asset needs some time to calculate all the geometry & surface alignment, so the larger the asset, the more lag it will cause.
In general, it’s not designed to spawn in game, it’s possible, but not recommended for larger amounts of assets. Especially that it’s not possible to convert in-game-spawned assets to Static Meshes (which is heavily recommended for good performance).
