Hi guys,

to install Unreal (4.17) on Linux, the installation can be done using scripts without any problem.

Since it can be done with scripts, I can put it on a Docker.

The problem is that when we open Unreal for the first time, we have more than 2k shaders compiling. If I put this on a Docker, whenever I run the Docker container, it’s going to compile from zero again.

So my question is: How can I compile the shaders using Command Line to be able to put it on a Docker?

Hi,

As this is the Editor and not a packaged game you would want to use a shared DerivedDataCache. If you take a look at the guide here Derived Data Cache | Unreal Engine 5.1 Documentation you will find more information on this. Adapting this for Linux, would be run as follows:

./Binaries/Linux/UE4Editor -run=DerivedDataCache -fill -DDC=CreatePak
