I have the same issue- more specifically, in the Chunks Fade In Settings, when Fade Enabled is set to No, reloading the chunks or exiting/re-entering the world causes all entities to become invisible.

Re-enabling Fade Enabled to Yes immediately solves the issue, without needing to reload chunks.

What is the issue?

• All entities, including the player model, become invisible after disabling the Fade animation

Conditions to reproduce

• Disable Fade animation and then reload chunks - or - Disable Fade animation, enter world

Does this issue appear only with Sodium, Iris and Chunks Fade In?

• Yes, when only those 3 are installed in the Mods folder, the issue still occurs
