Shared DDC setup
This topic covers the steps needed for configuring a shared Derived Data Cache - a “DDC” - to improve the startup speed of an Unreal Engine project shared across a RenderStream network.
The DDC is where shaders for Unreal Engine projects are compiled and stored. You may have noticed when opening a new project on a standalone workstation or on a Disguise render node that shaders need to compile for quite some time, even if the project is very simple.
One of the benefits of working with identical, standardized hardware like the Disguise rx range of render nodes is that the DDC can be compiled on one machine and then shared across a network to other nodes in the RenderStream cluster, eliminating the need to individually compile shaders on each render node.
