Beta Block Placement
by DuckHunt1337
Beta Block Placement changes how blocks settle when a player places them, aimed at correcting client-side prediction on Modern Beta SMP servers.
What it does
The mod targets a placement mismatch between the server and the client: a block the player sees appear may not match what the server records, which causes small visual bugs such as fences that connect to solid blocks they should not. The mod attempts to fix this on the client side, so only the player's game is changed. Servers do not need it; each player installs it for their own game. Beta Block Placement is meant to be played on a Modern Beta SMP server. Files target 1.21.1 only and are published for Fabric, under All rights reserved, so the code is not open source.
Key features
Face culling prediction
Corrects the client's prediction for face culling on stairs, slabs and longer slabs, reducing brief flicker on transparent blocks.
Stair placement direction
Adjusts the predicted direction of stairs so they do not turn to a different facing after they have been placed.
Fence connection fix
Reduces the mismatch that makes fences connect to solid blocks in a way the server does not show.

This mod attempts to fix the client side - server block placement mismatch which causes small bugs such as fences connecting to solid blocks for a brief moment. This also fixes the face culling prediction of stairs and slabs so you no longer have slabs and stairs that flicker transparent for a brief moment
