During V3 development, the scene’s depth seemed to fold. Rain, silhouettes, light, and fragments of the world occupied the same graphic plane. It did not look like the game. It looked like a storm collage that had escaped from it.
The dated field note says the glitch was unique enough to nearly qualify as art. The screenshot supports that feeling. It is a runtime artifact, not a planned cutscene or a later reconstruction.
The honest answer is that the cause is unknown
V3 has many systems that could affect a storm frame: rain, clouds, bloom, transparency, post-processing, scene order, and camera state. The public note does not include a reproducer or diagnosis.
Picking one of those systems would make the story tidier and less true. The image proves that the visual event happened. It does not prove why.
What happened next?
The image was kept. The wider V3 visual system continued with changing weather, rain, volumetric clouds, bloom, post-processing, and a quality governor. The source note does not say how this specific fault was corrected or whether it returned.
A useful kind of failure: fix the game, keep the picture, and resist inventing the missing detective story.
What the current record can say
The screenshot and dated builder note verify the broken visual state. The exact renderer fault and its later disposition remain unknown.
Medium and high V3 quality render bloom at half resolution to control cost. That fact belongs to the larger visual system and does not identify the cause of this frame.
