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"

How to drive Point Gravity parameter via blueprint on GPU Particles?

Hello, I'm currently using a point gravity parameter on my GPU particles. It seems like I can't drive the parameter via blueprints! All the other parameters do work. I really need this feature and I think it is a bug. Does anyone have a workaround or fix for this issue?

I have to use GPU particles since I'm using vector fields.

And yes, Param Mode is set to Direct and Seconds before Inactive is set to 0..

I'm afraid I can't help much, except to say that anything that is accessible in C++ can be exposed to blueprints by adding a C++ .h and .cpp file to create the blueprint node(s) that access it.

It's a bug, that parameter is not working, but the issue wasn't solved for a couple of years now so they closed it :(
