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"

Get Vector Parameter Values

I was wondering if the 'Get Vector Parameter Values' Array is bugged or I am not using it correctly.

I have a Dynamic material instance that I am creating on construct and saving off as a variable. I can access the variable to set parameters of any type just fine. However if I try to use the 'Get Vector Parameter Values' array from the dynamic material variable, it is always zero filled.

My test results in only 'Hello' printing out, or if i connect the array to a length, will return 0 (I am also using this Dyn material to set colors, so I know that it contains vector parameters:

I solved the issue, but I can only think of edge case scenarios where this would be useful (maybe there is a reason?).

The node only returns values that have been set previously during runtime. Not sure if this is intended or not.

I can confirm, this is correct. I was intending to use this for grabbing all the names from the material, but it's not useful if I have to hardcode set them in runtime before they're available in the array.
