Resource and Behavior Packs​

  • The player's "helmet_layer_visible" variable is now based on the result of the has_head_gear Molang query and the player and persona render controller's part visibility for the helmet layer no longer checks for the existence of head gear. This fixes attachable scripts setting the "helmet_layer_visible" to 1.0 to now properly work and maintains a fix that prevents persona hair and head gear from clipping outside of mob and Pumpkin heads (MCPE-183058) 

Sounds​

  • Specifying an invalid sound event in a sounds.json file will now trigger a content error 

Structures​

  • Fixed minecraft:structure_block debug bounding box rendering when clients initially load server worlds containing one

        }
        }
