Pale Hanging Moss is using an outdated block model on Bedrock Edition. This causes two visual bugs:

• Pale Hanging Moss is not stretched to fit the full block
• Pale Hanging Moss is not double-sided, creating an "ugly side" when viewed from east and west

Both these issues were already solved in 1.17 with the introduction of the Cave Vines block model. The Cave Vines model is stretched and double-sided, making it look correct from all angles.

Bedrock Pale Hanging Moss vs. Cave Vines

The stretched part of the Pale Hanging Moss is likely intentional. The purpose of the moss, as described in Minecraft Live, was to obscure the player's view. Stretched moss fills the gap between blocks, while the current model leaves large gaps.

The outdated Pale Hanging Moss model also creates a parity issue with Java Edition.

Expected Result

The Pale Hanging Moss model matches the Cave Vines model.

Observed Result

The Pale Hanging Moss model differs from the Cave Vines model. This also creates a parity issue between Java and Bedrock.
