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"

Beam Particle System Questions

Today, I've learned that I am absolutely TERRIBLY when it comes to particle systems. I've got a couple of materials set up - I started off following this guide:


I've made my own modifications to keep it straight and a single beam (not doing the weird things like the 3 beams were doing), but I'm not entirely happy with the result - the beam is too wide, and I'm not sure how to control the regularity of the pulses on it.

My goals:

1) Have a little "ball of light" at the end of the beam - I have a a texture that's just a white radial gradient on a black background, but I'm not sure how to use it.

2) (Perhaps) Animate the pulses so they move from source to target along the beam at a defined speed. Whether or not I do this is still in question - I'm aiming for a mobile platform, and I'm not sure how taxing this would be. I'm also not sure how difficult it would be.

If anybody could help me achieve these goals, it would be greatly appreciated. Thank you!
