## []()Turn on RDM per universe

If RDM is turned off in global settings, then it's indicated by a red **RDM icon** ![](/img/grandma2/icon_rdm-red_v3-2-3be191.png) in the universe pool, the following example explains how to turn on RDM per universe.

**Requirement:** RDM is global turned on. For more information, see [turn on RDM global](<#Turn on RDM global>).

There are two ways to turn on RDM per universe.
