I have little problem in unreal. I have free to use particle system and I want to copy it in other project. Copying is ok, but in new project particle system looks like that Screen capture - d2e42cb43d172cf62b011bfa5945beee - Gyazo . There is effect like raining and snow blowing, but in one project htey work, but in my map it looks like shape_plane . Is there some special way to migrate import particle effects
Is this particle a blueprint? Is there a chance that you copied the blueprint only and not the actual particles that are spawned inside the blueprint?
Problem solved
