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"

[Feature Request] Lightmap External Storage

Having lightmaps stored as part of the .umap file is fairly problematic for distributed teams (at least those without redundant OC-3 lines coming into their building). Any change that affects lighting causes the entire map file to be marked as a diff. This means hundreds of megabytes of data being pushed up and pulled down if even a single item in the level that affects lighting is changed.

Moving the lightmaps to some kind of storage external to the level file would be very helpful for distributed teams and much kinder to everybody's source control repositories.

Agreed. Downloading huge lightmap is really annoying on distant/poor network
