For some reason impact marks are not appearing on the textures, i have set a surfacetype on the material.
The impact marks do appear on another map with the same texture. So i have no idea how to fix this. It does appear on models tho.

It's fixed now, i selected pretty much the whole map and saved it as a prefab. Made a new map and pasted the prefab and now everything is working again
