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 create an "EMS" style particle system?

I'm trying to visualize an Electromagnetic Spectrum (Radio Waves specifically) via particle systems or possibly blueprints or even a Post-Processing material/unbound volume. Not really sure exactly how to get going with this.

Basically it would be similar in design to the Architecture of Radio app (Example here) where in the finalized version you could look around the game level, see various way-points over routers, cell phones, and other EMS emitting objects throughout the scene (I have the way-points working). Preferably the EM waves would also at times bounce off of walls and other collision meshes, while phasing through half the time (through the same objects).

Another example: alt text alt text alt text

P.S. My apologies if this is in the wrong section! And thank you anyone for their help!
