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"

Quick update: if i remove all blueprints then I can open the project, then I re-add them and fix compile errors the game can run fine. Close down the editor, can't re-open it! There are NO compile errors in my blueprints!

Another update: I got around the first "steamvr" scripts not being found by changing the loading defaults to "PostConfigInit", then my other plugins caused the same crash. Changing them all then causes this next crash, which can only be resolved by removing all blueprints (removing 1, then crashes on another blueprint that called that one)

The strange thing is only this project crashes, none of my other VR projects crash. There are no compile errors once I get the game back up by removing blueprints and re-adding them.

Solved my own issue. Removed all blueprints, opened game, re-added blueprints. Added catches for all default map blueprints to make sure no used pointers are null.
