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"

Changing Material Function Category Crashes Every Time

Recorded a video so you can easily reproduce: https://www.youtube.com/watch?v=vzvvH6AgckQ&feature=youtu.be

  • Create a new Material Function.

  • Check 'Expose To Library'

  • Try to type over the default 'Misc' category.

  • Recieve Crash

This caught me out when I created a function, didn't save then tried to expose it and lost work in the process. Not sure what's going on here! ScopedTransation isn't invalid by the looks of it, but it's 'Index' is 0? Whatever that means..
