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"

[BUG] Failed to open map file.

When I start a certain test projects level made just last night, I now get an error on start up this morning.

Failed to open map file. This is most likely because the map was saved with a newer version of the engine.

Rocket starts with an untitled level with nothing in it.

Are you 100% sure that you have opened the map with the same version of the UE4? It could be that you have 2 different versions on your pc ad you have opened it with the wrong one ^^

Yep, I have only been involved with the September release, only 1 installation of Rocket,

Hi Robert,

I will be helping with this issue. Can you please give me a copy of the project and level in question? I will run a few tests and see if I can not get to the bottom of this issue.

Thank you,

Alexander

Hi Robert,

I have been investigating the problem and am getting the error you are seeing. I have a couple of questions to help in my testing. Do any other projects give you this error? Can you create new projects without the error? Past the initial message, are their any strange behaviors in editor?

Thanks,

Alexander

I am having a similar issue and I think I can elaborate on the issue. I was creating my map for the past few days. The past few hours, every time I would attempt to move an object, it would freeze up for a few seconds before the move would register. It was very laggy for some reason. I know the map was very big, but still, the specs on my PC are more than enough to handle it. Regardless, I restarted my computer and when I attempted to re-open the file, it gave me the same message. This is extremely frustrating considering all of the man hours put into the map. Please, give me a solution so I don't have to move engines. This can't be a possibility while developing games, what dev would use it while running into issues setting them back days? Any help you can provide would be much obliged.
