StokieMokie.... and welcome
First, which version of fpsc are you using? (any mods) As some commands have changed from earlier versions.
Quote: "I used the "LED White" of the nomadmod"
These types of "flashlights" are weapons, they use the "muzzleflash" to produce a light.
It works great, if you are using the correct shader.fx, If not, the light will not show up/reflect on the entity.
Quote: "Thus, I tried out a flashlight script-the one from this topic"
These types of "flashlights" are simple a dynamic entity you pickup and then runs a script,
which in turn, shows a full screen HUD image across the screen (dark on the outside edges,transparent in the center)
and then turns up or down the ambience. This gives an excellent "Flashlight" like effect which looks good and is easy.
Your other problem has to do with which shader your using on your NPC character. Try this, I know it works.
Make a simple room (for testing) Place any ww2 characters (2 or 3) , some in the dark, couple under a light.
In the property settings change the "bumpbone.fx" shader to the "bump.fx shader. That's it. Test run and see.
Your characters now will be dark in no light, and the flashlight will reflect and show them.
My games never have bugs. They just develop random features..
Lots and lots of random features...
