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"

Emmit via bitmap

Looking for finer control of particle emission, wondering if I can use a bitmap or procedural noise map to trigger the probability of emission on a mesh? Relatively new to Cascade, I could be missing something obvious. I see that a mesh can be used, which could work. Not ideal. Read an impressive thread showing how to map csv data to position by encoding positional data into bitmap, that could work too. Thread started veer from my goal when it got heavy into point cloud territory, but it looks like it could be paired down for my needs. Would be excellent to paint heat maps for particle emission.

Any ideas?
