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"

Running launcher with a copy of unrealengine folder makes you download everything all over again

So at work i have a fiber 50Mb connection however at home i have a T1, and download 8+Gigs is a pain and time consuming. Basically i cant do anything else on the net then if i wnat this to complete as soon as possible.

Yesterday I downloaded everything at my office the copied the whole UE folder to my external Drive i take back and fourth home with me to then so i wouldn't have to then re-download all of what i did at work.

Now i do this alot with other programs I'll install the launcher, load the launcher up that way the launcher create whatver reg entrie sit needs and place sthe file structure needed. I then close the launcher and copy and past over the Unreal Engine folder over what I just installed with the launcher to save time downloading everything again and bam done.

However Every time i load the launcher up it wants to re-download the whole entire program and doens't see I have any of the free content i've downloaded from the market place.

I've even tried putting the folder I've copied in 1st before installing and same thing.

is this a bug or intended or any planes to allow one to do this???

It looks like the 1st one does for the most part, the 2nd post I did find but it only mentioned the projects folder so didn't fully relate.

any plans to change this in the future because thats a nightmare not just for the downloading of the UE4 but any content from market place to. What about so-called updates i'll then need to download. Will it be like an image(current install gets replaced by another updated 7+gig install) or will it be incremental(only files needing updates will be updated).

Right now, the Launcher will not recognize any projects copied from another location, so it will try to download it again. It's a known issue, and the team is looking at ways to improve the Launcher so you can move project content between systems.

For updates, the Launcher will search the installation for files that need to be updated, much like Perforce, so you likely won't have updates anywhere near as large as the initial download. There is unfortunately no way to get around that initial download size through the Launcher.
