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"

Demorec Replay Demo recording failure

Reproduction Steps

1 Create New Project (Third Person BP Template)

2 Play

3 Open console

4 Use the demorec command

Output Log

am getting the following console output:

 Cmd: demorec <test>
 LogNet: GetLocalNetworkVersion: GEngineNetVersion: 2872498, ProjectName: replaytest, ProjectVersion:, InternalProtocolVersion: 9, LocalNetworkVersion: 1044399586
 LogDemo:Warning: UDemoNetConnection::ReplayStreamingReady: Failed.
 LogDemo: StopDemo: Demo <test> stopped at frame 0
 LogNet: UNetConnection::Close: Name: DemoNetConnection_0, Driver: DemoNetDriver DemoNetDriver_0, PC: NULL, Owner: NULL, Channels: 0, RemoteAddr: UDemoNetConnection, Time: 2016.03.21-18.46.32
 LogDemo:Warning: Demo recording failed: Couldn't open demo file <test> for writing

When I try recording a second time, I get the following output:

 Cmd: demorec <name>
 LogNet: CreateNamedNetDriver DemoNetDriver already exists as DemoNetDriver_0
 LogDemo:Warning: RecordReplay: failed to create demo net driver!

Obviously I also cannot DemoPlay, since there is no recording created. Do you know if there is a workaround or other help?

I only now figured, that replay is working when playing in standalone. Also in 4.11 preview 8, you get a warning, that demo recording is disabled in Play In Editor (PIE) mode.
