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"

Particles are not following the vector field properly.

I am trying to use UE4 are a tool for visualizing scientific data and using particles to show field lines seemed like a good idea. However, even though I made a mathematically perfect flow field I was unable to get it to follow the field properly. I made the field global and I made the particles have a tightness of 1. No matter what I did the resulting lines spiraled in to a point or out of the field even though it should be a perfect circular motion.

Further, when looking at the same spiral from above I could see that it was pulsing slightly. Growing larger, then smaller, then larger again. Is there a way for the particles to obey the field perfectly? Or is it not going to be accurate because of optimization steps taken?

I am not afraid of coding and I might be willing to remake the entire field or the particle motion system. The only idea I have is to write an algorithm that spawns a billboard with the material of choice and place it around inside manually using C++ or making a custom shape by generating a thin tube to represent the shape.

Any input would be very helpful.
