Create a new material, and add a TextureSampleParameter2D (=Parm2D) expression instead of a regular TextureSample.

"You can't change the material applied to a static mesh actor during play. If you use an InterpActor, then the Set Material action in Kismet should do what you want. Or you could use a material with a TextureSampleParameter and the Set Material Param action should allow you to change that in Kismet. There are other ways as well, but I think one of those should work in most cases."

Convert a lamp mesh so it has a Material with an Emissive feature and an alternative Material with no Emissive feature, creating the illusion of a lamp being turned on and off.

Use the Set Material actions in Kismet to set the material of a surface.

This only changes the Material on a mesh: it does not the light cast in the scene. Use PointLightToggleable to provide light that toggles.

Create a new material, and add a TextureSampleParameter2D (=Parm2D) expression instead of a regular TextureSample. Fill in your texture into Parm2D expression, as if it were a regular TextureSample, and also be sure to set a ParameterName. The name will be used to identify all the expression in Kismet and the Material Instance later, so pick something descriptive.
