# Network Replication

### About  


- Most entities have either **networkReplicated = false;** or **networkReplicated = true;** near the top of the entity outside the edit field. They determine how entities are broadcasted to clients, but they often create many visual issues or crashes when set to true.
- For example: a network replicated door obstacle will have a positioning offset that is located at a slightly incorrect location for clients. The effect is greater the farther away the entity is from 0, 0, 0 or the world origin. This applies to every network replicated entity but the effects are gradually more noticeable from further distances.
- Network replicated entities located beyond the coordinates of **x = 800, y = 800, z = 200** will be unplayable for clients.

<p class="callout warning">Entity offsets are roughly 0.6% closer to the coordinates of 0, 0, 0 for clients. The host does not experience this issue.</p>

<p class="callout success">There are ways to work around entity offsets (see [Entities](https://wiki.eternalmods.com/books/9-multiplayer-modding/chapter/entities)). As of the current versions of modded multiplayer, only the AI suffer from entity offsets.
