Replace Selected Actors with

Hello - who can help me.
when I change a Static Mesh to e.g. a Point Light (by “Replace Selected Actors with…”) it disappears in the active level editor viewport when I press the playbutton

Is the point light truly disappearing and not contributing any light, or is the icon just disappearing? Whether in Editor or Play-In-Editor, you can use the “G” key to preview what the game should look like.

There are two other things that can happen if objects disappear only during gameplay. If you are using Sublevels, maybe the object is in a sublevel that is not streamed in. You can set it to be “Always Loaded”. Or if using World Partition, the cell with that object might not be loaded. You can turn streaming off temporarily to check or manually load those cells.

It shouldn’t really be caused by the actor replacement functionality.

Hi Stephen,
thank you for your answer. I`ll come back when I have succes.
