| $git clone --single-branch --branch ue5-early-access --depth=1 https://github.com/EpicGames/UnrealEngine.git | |
| # was ultra slow 10KB/s. But, on south america at least, when it was about 23h, the speed went up to 1.5MB/s! | |
| # I was trying many ways to resume a clone download UnrealEngine/.git/objects/pack/tmp... file, but it is currently impossible. | |
| # The .zip download cannot be resumed also!!! :( | |
| # I tried also to create a local branch, renamed to ue5-early-access, and was trying to fetch it in some way, but the internet speed up. So this is the next step if nothing works again later... | |
| # SO, THERE IS STILL NO WORKAROUND! :( |
