When implementing Volumetric Clouds in a splitscreen game, the clouds on the second player's screen render incorrectly. If the Two Player Splitscreen Layout is set to Vertical, then the clouds render as a grey gradient at the top of the player's screen. If the Two Player Splitscreen Layout is set to Horizontal, the clouds do not render at all.
This issue does not occur, when setting the number of players to two or more and choosing any of the Net Modes in the Active Play Mode options.
Not marking as a regression, since Volumetric Clouds were first introduced in 4.26.
The Volumetric Clouds render as a flat gradient for the second player
The Volumetric Clouds would render the same for both players
There's no existing public thread on this issue, so head over to AnswerHub just mention UE-111894 in the post.
