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"

some "Distribution Float Particles Parametrs" can't be controlled from a BP ?

My problem - some (float) parametrs can't be controlled from a BP. Please see my attached image for details. On screenshots you can see: size and rad params work well in runtime but the "nn" param (how many particles are spawned when particles effect occurs) is using always the default value from the Constant in distibultion section (1.0 value as indicated by a red circle).

Since only some of the parametres do not affect the particle system i wanted to know if this is a bug on the engine side or something that we are missing here.

Is there any other way to spawn an exact amount of particles (specified in the BP) on the current frame ?
