1. Open empty scene
2. Place Spline Mesh Actor
3. Import attached static mesh test_box.obj
4. Select it inside Spline Mesh Actor (Static Mesh field)
5. Reimport test_box.obj

How does TextureRenderTarget2D get TArray<uint8> type data?
Why does the REMOVE method of map container remove elements have memory leaks?
What is the cause of the packaging error falling back to 'GameUserSettings' in ue5?
What is the difference between Camera and CineCamera?
How do I set a material as a post-processing material?
How to delete some elements correctly when deleting an array loop?
