[@okasareru7226]

Thank you my guy! Kept running into errors until i found your video.

[@RafaelRodrigues-jq6uc]

Bro I wish I've watched this earlier, saved so much time. Amazing video

[@3BEEZ]

Great tutorial, very easy to follow.

[@BetideStudio]

Happy to hear that 😀

hi; i downloaded the 4.26 from the Zip as you did, i did what you did in this video, but at the end, when i open my Built Unreal, i can't open my previous project, created with UE_4.26 from the Launcher Epic Game. It says that it doesnt have the same version or matching version. But both are 4.26 i dont understand why it doesnt work. I also can't install plugins which are available for 4.26 Someone have an idea? thanks!

[@vindeep1421]

thanks for the tutorial

[@TECHTOUR]

plugin bridge failed, any solution to the error?

[@DildegaLakdilu]

May I ask how much disk space will it take up after everything is completed?How to clean up if the occupied disk space is too large(190G)?😭

[@gamertech4589]

Can share source build unreal for 5.1, 5.3 ? Every one doesn't can't compile if one person can do rest can use it

[@Seb851s]

Yes, but only for non-programmer team member with UnrealGameSync

[@Jean-ChristopheMazza]

I get these errors at the end of building, tried m,ultiple times. Any idea?

[@lukeellis2939]

Thanks for this great tutorial helped alot :)

[@BetideStudio]

Glad it helped!

[@sekker2k446]

Very useful for rookies. Ty Bro!

[@sammtanX]

Can we know what is the approximate overall size? (Including the early files downloaded from github and final build directory)

[@abuhurairazahid]

arround 160GB

[@joshcruzmadeit]

great thank you so much!

[@BetideStudio]

Glad it helped!

[@showcast4371]

So how can i open my projects on this source build from documents

[@arphenti2502]

I don’t know what I am doing wrong, but after doing everything, and creating a new project, editor just won’t launch.

[@zodiacman6802]

Thank You!

[@showcast4371]

Does generating project files require internet connection

[@BetideStudio]

Nope, as far as I know.

[@ajitsinghyadav1725]

Nice.. 👍

[@showcast4371]

Can we open an already made project or we have to start by making a new project after making or completing this build

[@BetideStudio]

Yes you can :D

[@LMAO_GG]

What does ue5 source build does

[@BetideStudio]

Normally used for building dedicated servers and editing the engine itself

[@RevolverLee]

Is there a way to update without having to download the source code again?

[@BetideStudio]

None that I know of sadly. Because it requires file download and building

[@maloxi1472]

Yes. Instead of downloading the zip of the repo, clone it so that you only have to download the deltas to update your local copy of the repo. You can even truncate the history while cloning so that you don't have to download too much data

[@RevolverLee]

@@maloxi1472 so when you're cloning of the repo, is it essentially all the files as if the source has been fully built. So you don't need to rebuild via visual studio each time you update?

[@unrealengine5-storm713]

19 hours!? Dude. No way. Noooo way. I have an i7 9700k and it takes 3 or 4 hours TOPS

[@BetideStudio]

It does for a lot of people xD

[@dhruvsakariya3129]
