Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Probably the latest version is your best bet -- but 7.3+ has worked for us. Do a search for the file BuildConfiguration.xml (there seem to be a few but the one that works for me is in AppData/Roaming/Unreal Engine/UnrealBuildTool). In there set the tag to true. The next build from visual studio should pick it up. HTH!

Hi ggalt, Idan from IncrediBuild here, glad to see you're using IB with UE4.

In a nutshell, you don't need to do anything special in order for Unreal to accelerate your compilations using IncrediBuild. Once you have IncrediBuild set up in your machine, Unreal will automatically use it for compilation acceleration (make sure you have multiple Helpers for performance).

What you CAN do to boost the experience is add Shader acceleration (set r.XGEShaderCompile = 1 in ConsoleVariables.ini for faster-distributed shader build times.) Here's a tweet a fellow IB/UE4 user shared on the matter: https://twitter.com/keefjudge/status/638701482360066048?lang=en

Happy accelerating, Idan The IncrediBuild team

Hi idannotamago,

Is this still working in UE 4.20? I installed https://www.incredibuild.com/FreeVisualStudioLicense and while it worked great for building code, I didn't see shader builds getting distributed.

Hi Audonator,

Our team looked into this problem and it appears that Unreal Editor uses a specific path to determine whether IncrediBuild is installed: "C:\Program Files (x86)\Xoreax\IncrediBuild\xgConsole.exe"

Since in recent versions we changed our default Installation path to "C:\Program Files (x86)\IncrediBuild" this file is no longer found by the editor on new installations (Upgrades from previous versions of IncrediBuild still use the old path).

We are working with Epic Games to resolve the problem, for now, our recommendation is to uninstall IncrediBuild and reinstall it into the "C:\Program Files (x86)\Xoreax\IncrediBuild" folder where Unreal Editor looks for our files. Note that this only needs to be done only on the machines where the Unreal Jobs are initiated from.

Hi all, I wanted to update you that the bug that could cause Unreal to not detect IncrediBuild in the new installation path was resolved in the latest Release of the engine - 4.21.

With this version, you can have IncrediBuild installed under any path, and the detection will work correctly.

Thanks, Idan from the IncrediBuild team
