Penumbra flashlight in Amnesia?

[DIGI Byte]

Ok, so.... I imported the model into the model editor and saved it, added a spot light and so on, I copied the files over the lantern to see it quickly ingame if its facing the right way nad so on
...
but when trying to pull out the flashlight in game the game freezes and closes with a crash dialog,

I'm obviously missing something... or did something wrong

lets start again from scratch, I got the model... in the model editor... what do I need to make it in game?
does it need every texture? do i need to create a texture file? do I need to create a physics?

i'll try from scratch and make a new build, i'll go over the wiki again but I don't know what I missed
