Fishing Simulation Guide Hub

Physical fish, shoal behavior and the rendering method behind the glowing catch system.

Quick answer: Fishing is not a random roll: hundreds of individually simulated fish follow one another or the bait, while their glow uses a quarter-resolution texture to control GPU cost.

What the confirmed data means

The official optimization report provides unusually concrete information about both gameplay and rendering. Separating physical catch logic, group behavior and glow rendering creates useful pages for mechanics, strategy and performance without inventing species tables.

How to use this information

Release testing should pair observation with capture data: identify a visible fish, present bait, record movement and confirm that the caught individual matches. Performance tests should compare the same scene and shoal under fixed settings.

Publication boundary

Species, bait preferences, rarity and sale values remain unavailable. Technical implementation does not reveal a complete fishing database.
