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"

Particle sprite disappearing with set fixed bounds

Hello,

I am trying to create a GPU sprite particle system simulating an fiery cloud effect that is larger than my current viewport. I have found several tutorials recommending that I check the "Use Fixed Relative Bounding Box" and set the bounds to -100K and 100K.

However, when I apply these changes to the particle system, it seems to have stopped emitting any particles entirely.

For reference, this is what my particle emitter should look like. This is my emitter without the fixed bounds selected:

Any help would be appreciated. Thanks in advance!

You have set the min and max values the same so the box size is zero

Try min values smaller than max or negative -100000 in x,y and z

That did the trick! It must have slipped my mind about needing the box size to equal 0. Thank you for the help!
