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"

Spawning CPU particles overlaps weird.

latest preview. (.3)

So this is rather odd, I was testing something else in 4.15P1 and I noticed that occasionally GPU particles would emit rather odd. I wanted to post about it, but didnt have any time. I just tested the same situation in 4.15P3

And this is Preview3 (CPU on left, GPU on right)

Ignore the brightness change, was to test something else.

the only thing changed here module wise is a spawn module with a rate of 10, and a constant of 20. the only difference between these two emitters is one being a GPU, and the initial location to have the two next to each-other for comparison.

Left: CPU, Right GPU

Hi Luos,

Would you mind sharing the particle system asset? I ran a quick test of my own and didn't see the behavior shown in your GIF. I just want to compare Particle System settings.
