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"

The sound effect used for the advanced vehicle template is Engine_Loop_Cue. If you open that you will find it contains a Crossfade by Param node, which is what blends between different samples for different RPM values. You'll notice that the last entry for it has a fade out distance start of 2500 and fade out distance end of 3000.

This is slightly confusing as these numbers don't refer to distance here but the RPM that's being passed from the vehicle to the audio component. This means that when the vehicle gets over 2500 RPM after you've changed the maximum it will start to get quieter. If you simply want to prevent this, then change both values to a very large number that your vehicle's RPM should not reach. If you're looking to extend the range of this sound with more samples then you would add more inputs to the Crossfade node and blend them together.

Hope that all makes sense.
