By the way, did you also copy CC_Shader? Were you using "new" UE 4.26 project or you were using UE 4.25 convert to UE4.26 Project then input Auto setup for 4.26?


try this

AutoSetup does not work with a c++ UE4 Project.  :-(
When building,
error LNK2001: unresolved external symbol IMPLEMENT_MODULE_RLPlugin

It works fine with a blueprint based projects.

Completely true. The only workaround is to add the plug-in directly to the Unreal installation directory instead of the project directory.

Thanks Ricardo  - Gonna give that a try now....

You got it. I was banging my head against it just a couple days ago as well, so I know the feeling :)
Just to be clear if someone else finds this thread. The content folder that has the shaders still goes into the project directory, just the plug-in folder goes into the UE installation dir plug-in folder.

The final step is to enable the plug-in inside UE on the plugins menu option.

This does not work, the moment you add the CC plugin to the UE plugin folders it tries to compile it and it fails. If you move it to the project plugin folder instead, it tries to compile it there and again it fails.
There must be some flow which tells UE not to try to build it, but just use it as it is. Off-topic, it is annoying that CC plugin is closed source, I don't believe there is any worth of IP to protect.

P.S. The solution is to uncomment/add the following inside the \Plugins\Auto_Setup_1.11\Source\RLPlugin\RLPlugin.Build.cs

bUsePrecompiled = true;

bUsePrecompiled = true;
