step
1. First search for the following assets in the Unreal Mall and then create a project
2. Open the new sample project and create a new blank level
3. Drag "BP_DemoRoom" into the viewport
Here set "Base Room Size" to 5
Populate “BP_DemoDisplay”
Here "Description" is set to "Standard Sprite Emitter"
Use the Alt key to quickly copy "BP_DemoDisplay"
The "Description" of the second "BP_DemoDisplay" is set to "GPU Sprite Emitter"
In the same way, set the "Description" of the third, fourth, fifth and sixth "BP_DemoDisplay" to "Mesh Emitter", "Bean Emitter", "Ribbon Emitter" and "AnimTrail Emitter" respectively.
