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"

Short particle burst

Hi everyone I was just curious to know how I could make a short little particle effect explosion for my shipyard. What I wanted was a small explosion of air as the umbilical cord detaches from my ship. So far tutorial I have looked at haven't been useful and most important of all is I need it to be controlled in the matinee so it will happen about 45 seconds into the animation.

Many thanks Alex

Hi Alex,

The Content Examples project has some good particle systems that you can use as a starting point for the air explosion that you want.

You can also find a great set of tutorials for creating your own particle systems here: https://www.youtube.com/playlist?list=PLZlv_N0_O1gYDLyB3LVfjYIcbBe8NqR8t

Here are the steps you can take to activate a particle system through matinee:

  • In the Required module of your particle system, set Emitter Loops to 1

  • Also in the Required module, set Emitter Duration to the amount of time the effect should last after becoming active

  • Drag the particle system from the content browser into the level and position it

  • In the details panel of the editor, uncheck the Auto Activate property of the particle system

alt text

  • With the particle system still selected, open matinee

  • Right click in the Tracks panel and select Add New Particle Group

alt text

  • Choose a name for the group and press enter

  • Select the particle group track and scrub the timeline to the 45 second mark

  • Press enter and select Trigger, then click OK

alt text

You can actually trigger the effect multiple times in the same matinee if you so chose.
