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"

Prevent wide beam particle emitter from rotating towards camera

I'm trying to make a particle system for a weapon which shoots a flat wide beam, but having some difficulty. I was able to make something close to what I wanted using a beam emitter with a large X size. But, the problem is that I can't figure out how to force it to always be flat and not rotate towards the camera.

The particle system is spawned attached to the weapons muzzle, and the target is set as the result of a singe line trace. Everything seems right except that it rotates slightly to face the camera. Is there any way to prevent that? I've tried everything from using Orientation Lock Axis, to every type of Screen Alignment available and can't figure out how to get the desired result.

Here's what I have set up right now: alt text alt text
