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"

Perpetual wind strength variation (with no trigger). Can it be done?

Is it possible to have variation in wind strength without any trigger? My purpose is to make cloth assets look more natural in the wind. No wind is perfectly constant and some gusts of wind blowing from time to time would make assets affected by wind look more realistic.

I'm using APEX curtains made in 3dsMax with Nvidia's Physics Lab plug-in. Can it be done in blueprints yet? Someone found a workaround here that may work, but it is triggered by the character overlapping a volume. I need the strength variation to be permanent (and random if possible) and not related to the character in any way. Can anyone help?

Blueprints, no, not unless someone does the following first:

Take a look at the SpeedTree wind generator in the engine source by searching for "FSpeedTreeWind" and you'll see what is involved in making the gusts. So all you need to do is make an actor that can do that and it should work as you expect. Enjoy and yes, it is not an easy problem (hence why no one could respond for quite a long time)!
