I want spawn lots of game object far way from camera , with effecting the game pay. I manage to spawn the objects , but the problem is when I spawn the object game stop for split second and start Continuing normally , how can I avoid this ? I try the “IEnumerator” and “startContnue” but it’s still happening. I really appreciate for any help

Thanks

try to put each object in a prefab. prefabs are “preloaded” and have nearly no instantiating time.
