My Thumbnail generation plug-in is developed based on the UnrealEngine Editor. It has an independent rendering window and can output thumbnail images in various formats such as PNG, JPG, BMP and GIF. The main supported rendering objects include StaticMesh, SkeletalMesh, Material and AnimationAsset. The plug-in can generate a large number of editor default asset thumbnail images with one click. The GIF dynamic image is bound to the skeletal animation, and the loop time is the Animation Playback time, which can ensure seamless connection in the first place. The plug-in comes with many useful functions, such as focusing the model, switching perspective types, and supporting PNG model cutout. It also supports flexible customization of viewport scene rendering, including PostProcessing, Lighting, Bbackground styles, etc.
