Custom FOV
Custom FoV is a modification that gives players complete control over field of view parameters. All settings are located in the "Video" and "Accessibility" sections of the game options menu. You'll be able to finely adjust view changes during flight, aiming, underwater immersion, or under the influence of various game effects.
Unlike the standard system, Custom FOV separates speed-related field of view changes: one for sprinting and another for potion effects.
Mod Features

Field of View Effect Mode
Allows selecting one of four options: use all view changes, only standard (vanilla) changes, only changes added by the mod, or completely disable all view effects.
Field of View Effect Scaling
Individual scaling settings for field of view changes in various situations: speed, sprinting, aiming, flying, and underwater state. The adjustment range for each effect is from complete absence (0%) to maximum intensity (100%). These parameters work together with the general "FOV Effects" setting that determines the overall scale of all changes.
Important Compatibility Note
This mod is incompatible with Optifine, as the latter removes an important field necessary for this modification to function. For optimization and graphics improvement, we recommend considering alternative Optifine options.
