Summary

When having two intersecting/bordering day sequence devices that affect fog, running between them can sometimes cause a flash to occur when passing the intersection line/bordering line.

Steps to Reproduce

  1. Create a day sequence device that is a trigger volume, affects sunlight and disables sun component and flare, affects fog and enables fog component with 1.2 density, affects skylight with skylight component enabled, and affects sky with sky atmosphere component enabled.
  2. Copy and paste this day sequence device and move it over so that the two zones are intersecting
  3. Launch session and run between where these two zones intersect. The lines at which their trigger volume borders intersect eachother is where you should experience the flash.

Expected Result

When running between the said lines, you should have a seamless transition between the two day sequence zones as they have the same settings.

Observed Result

When running between the said lines, you experience a flash pretty often, but not everytime.

Platform(s)

Only tested on PC.

Additional Notes

The lower your graphics setting, the more noticeable this flash is, so when testing its probably best to be on low to observe the flash. If you’re playing on my version to see this flash, in your session go to the bordering forest and go to somewhere where the day sequence zones intersect and run between their bordering lines.
