WRAITH_TRAP is a new object in place of the hardcoded Animating from TR4. Used to trap the Wraith entity. Object is transparent so in theory anything can be used as the wraith trap.
OCB 0: Original TR4 effect
OCB 1: Enhanced effect where the wraith is pulled into the trap.
The trap from TR4 is in an animating slot in the download. Transfer it to the WRAITH_TRAP slot for it to work.
