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 scaling and loop problem

Hi! Is there anyway to make a loop particle system scale only one time at first?

I have created a particle with SubUV and "Size Scale" module, and I want my particle only scale one time and then keep looping the subUV animation part.

Now my problem is the particle keeps rescaling. I can't change the spawn rate(number?) because if I set the number more than "1", I can see the rescaling emitter overlapping each other. Also if I change the "Lifetime" module setting, the particle looks strange too.

Use "Size By Life" node. Draw a graph where You want it to grow, and it will stay that way for eternity (until death).

Hi S-ed! Thanks for answering! I tried both "Size By Life" and "Size Scale"'s graph but nothing changed. Particle keep rescaling when it finish last scale.

I think I need to see video/gif to understand Your problem more.

You could use ScreenToGif or OBS Studio.

Hi S-ed! For some reason I can't upload the video or gif or any image here. Maybe I'll try other way to fix this problem. Still thanks for answering and helping :)
