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"

I'm going to bump this since I am experiencing the exact same issue and have not found ANY kind of answer anywhere. The only thing I can add to this is that it's happening everywhere I can add arrays. For instance, it doesn't work in Material Parameter Collection just as it doesn't work in Landscape Grass Types. This is a really irritating bug with no apparent fix and it's driving me insane. If the original poster of this issue found an answer then PLEASE post back what it was so no one else goes through the struggle.

I found the solution and I'm posting here to save all of you the trouble. I hope you find this longer than it took me.

Open up whatever is blank, be it the MPC or a Landscape Grass type, whatever. When you open it, click on the window tab, and make sure that DETAILS in the top has a check next to it

Once you check that, everything should come back up and you should be able to use as normal.
