+### *particles*
+
+Particles are specified as a JSON object. Property names can be found [in the particles section](particles.md).

+When camera is near to the block, the engine will create an emitter that will run
+until the block is destroyed or the camera moves away a certain distance.
+
+### Material - *material*
+
+Defines the name of the block's material in the format `pack:material_name`, which affects the selection of block interaction sounds.
+Material definitions are located in /block_materials.
+
 ## Variants
 
 Some properties can vary dynamically, depending on the variant number stored in the user bits of the block.

 ## Варианты
 
 Некоторые свойства могут варьироваться динамически, в зависимости от номера варианта, хранимого в пользовательских битах блока.
