I See You Over There !

Adds additional options to the render distance of entities and block-entities.
Can fix the lower render distance on small entities, and automatically increase the render distance when zooming in.
This should theoretically work with any zoom mod.

This may not work as effectively in multiplayer. Unless the server is configured to have an increased tracking distance (vanilla settings), the client will not even know about far away entities.
In singleplayer, the mod automatically adjusts the tracking distance to match the render distance.

Configuration

The config can be edited in-game using Mod Menu + Cloth Config

fovScaling

When enabled, causes entity and block-entities render distances to increase or decrease based on the FOV (e.g, when using a spyglass). 90° is used as the identity.

When enabled, all other settings scales with the FOV, except for entity.max.

entity.min

Forces all entities within this range to be rendered, regardless of their sizes.

entity.max

Prevents entities beyond this range from being rendered, bypassing entity-specific logic.

This setting is intended to serve as a limiter. It is not affected by FOV-scaling, and will override the Minimum value.

block.min

Renders all block-entities within this range. This can only increase block-entity render distance, not reduce it.

block.beacon

Render distance for the beacon's beam.
