Thanks.
I will look at all those points you brought up. The jump boot's thing needs to be looked at. A guy on map core was telling me better ways to use blocking volumes in stead of the default collision mesh’s on some objects to improve performance so I have done that too all the spikes. I think as you said I will add a kill volume so if they use jump boots they will die once they jump over.
At the moment my desktop has the blue screen and I am trying to fix it. Hope this restore point works. So that’s stopped me working on it all day. But everything is backed up
Thanks again
