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"

4.16 Project to 4.19 & 4.20 - MorphTargetWeights Crash

I have a project that runs fine in 4.16 and is fine when I upgraded it to 4.18 through the launcher however when I use the launcher to upgrade it to 4.19 and 4.20 it crashes (see log below) when I start to play the game. Appears to be related to morph targets

The following error is from 4.19 log :
