Summary
Post process volumes can break at seemingly random intervals upon game save. This breakage is not visible until map reload.
Steps to Reproduce
- Have a global post-process volume *
- Make a non-global post process volume **
- Save the game
- At random, but fairly rare intervals, post process volumes do not work properly on reload
*Unknown if necessary
**Unknown if number matters, map prone to it has 7 non-global.
What I expected to happen
Post process volumes to not have their settings ignored and half-implemented in an odd way at random save intervals.
What happened
This issue has happened on my map about 5 times, leading to manually replacing 7 post process volumes, in the exact same spots, every single time, usually multiple times until it “takes.”
Notes / Media
The bold parts here are the “summaries” for each point. This is an attempt to make it more readable.
- The way you save the game does not seem relevant, at the very least it can break both with workshop “save to file” as well as the quicksaves.
- It does not seem tied to particular actions. I have had it break, recreated steps exactly (down to writing down exact item placement positions) and had the second not break, with multiple attempts trying to recreate the conditions for breakage.
- It seemingly breaks during the saving process. Workshop uploads require you to save a distinct file, you cannot choose an existing one. I had a file, and saved an exact mirror for upload. The mirror save broke. I then relaunched the game, reloaded the original save, re-saved and reuploaded to workshop. No breakage, with absolutely no changes done.
- Paradoxically, it does seem to break in “spurts.” When it breaks, it is more prone to breaking at similar timeframes. As an example, you can save a file, have it break, reload an unbroken save just before the breakage, do completely different actions, and still see it break. BUT: It seems to take a similar amount of time to do so; if your backup save was 2 hours before it broke, it will tend to break the save again, after around 2 hours. (This is much more vague “gutfeel” than the other points here.)
- Once fixed (by copycatting all of the post process volumes, and replacing them in the exact same spot,) it can sometimes break the replacements multiple times. When you replace them again, repeatedly, eventually it will “take.” It does not always “take” all of them at the same time, and often each replacement wave “fixes” only one box. It can take anywhere from 1-5 waves of identical replacement copies to replace 7 volumes.
- Oddly, when broken, the post process volumes aren’t completely ignored. It still fully observes pixellation settings. It doesn’t seem to keep grain, or contrast. It seems to half-do chromatic aberration? I’m unsure of other settings, since I’m going off of eyeballing it.
- Relaunching the game, or saving again over the broken save with the same save in a vain hope it fixes itself, does not fix this.
- Breakage is visible in broken saves in editor, gameworld, and live uploads.
- This bug has been present at least since the patch I joined the game. I don’t know how old it truly is.
- Irritatingly, I have not found a surefire way to reproduce.
