Recompile plugins for Unreal from Source code (Git)

Hello,

I am using a source code build from the Unreal-Engine (NVidia RTX-Branch, as an archvis-company we prefer this version of Unreal because it can utilize much more shadowed lights).
I am not a programmer or coding specialist, but I am kind of familiar with recompiling plugins for these specific Unreal-Editors. This is not a problem for plugins that normally get installed by the Epic Games Launcher using one of these solutions:

  1. via VisualStudio
  2. via RunUAT.bat

Unfortunately I do not manage to get plugins recompiled, that come with their own external installers:

In my case these are Axyz Anima and Connecter from DesignConnected.

Is there someone out there that could assist me in recompiling one of them?

Thank you very much!

Carsten
