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"

Temporarily force load all streaming levels from Command line?

This is going to sound a bit off but I have a unique request and it would be easier to explain my situation and my needs:


  • 1 persistent level

  • Many streaming

  • levels within Streaming levels are

  • not being loaded by default when

  • persistent level is opened. We

  • initiate automatic lightmap bakes

  • from the command line World

  • composition is enabled


  • Need to initiate a lightmap bake from the command line

  • For these automatic lightmap bakes we need to load all streaming levels within our streaming level

The Problem: Because we initiate lightmap bakes from the command line, when we open up our Persistent map the streaming maps aren't loaded by default. Meaning when we bake the lights for the Persistent map it is only baking the lights for the empty persistent map, not any of the streaming levels because I don't know how to do this(http://i.imgur.com/rcC5WhR.jpg) from the command line.

So the question is, how do I open up a map from the command line and have all of the streaming levels load within a persistent map that has world composition enabled?

We have the same issue here, anyone with a solution for this?

Do we have to modify the engine and add a flag to force the loading of our streaming levels or this option is already available?
