  1. Set something in construction script, for example add a few meshes with random locations in range.
  2. Add Skeletal Mesh Component.
  3. The blueprint will start ticking the construction script every frame in editor, which can slow down things massively when construction scripts are more complicated. Just look at the thumbnail, it will generate new locations (or whatever is set in construction script) every tick, resulting in chaotic, fast ‘dance’ in the thumbnail. It is present when hovering mouse cursor over content browser.

Here is a simple demo project: DEMO PROJECT
