The CryENGINEŽ 3.4.4 "Winter Edition" update features a modified version of the forest level that is included with the free SDK, helping users to learn more about adding a touch of sub-zero style to any environment. Major highlights of the update include the refactoring and development of a new entity for simulating weather called the snow entity. Similar to the rain entity this feature applies a frozen material layer to all objects within a set radius, and has been improved since early iterations to enhance performance.
