The missing sounds aren't a bug, but you need to add those yourself (they may have forgotten to add the sounds)
You need to change each fpe in the files/segments/modernday/..... (don't forget the fpe files in each ceiling folder)
Look for
;Segment Parts and then locate the floor '
floor_a.x and then find
materialindex0 = 0 Change the 0 into a number between 1 and 6.
Here are the sound that the numbers imo correspondent with:
1 = outdoors floor (terrain)
2= indoors floor (corridor)
3= metal floor
4= indoors floor (small room)
5= indoors floor (large room)
6= water
Also the doors don't have any sound. Find all of the fpe files for the door in this folder files\entitybank\modern day\doors.
Locate the
soundset = and
soundset1 = and change them into
soundset = audiobank\ww2\scenery\doors\open.wav
soundset1 = audiobank\ww2\scenery\doors\close.wav
for example. Those sounds are from the WW2 doors, fitted best imo.
I think they overlooked adding sounds to the floors and doors. I was hoping for some new character and door sounds, but it's not in the content pack at all, unfortunally.
Be inovative and creative.... don't create a fps with FPSC.
