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"

GPU Particles render in editor, only a few render when playing .

I have a load of GPU particles in UE4 for stars. They render fine in-editor, but as soon as I hit play or simulate they all disappear except for maybe 4 or 5 out of hundreds and hundreds. I'll attach before-after images to show what I mean below.

Using normal particles would be fine too, but they completely disappear when playing! Other particles in the scene are unaffected.

Thanks in advance. :)

Hello Anja,

Have you set the bounds for the gpu particles? Not doing so is the main reason they wont appear. Also, keep in mind you will need to restart ue4 after setting it, else it wont have any effect.

Hey Luos,

I didn't realise you needed to restart after changing bounds, however this has not rectified the problem. 99% of the stars still disappear in-game. :(

Thanks for your suggestion.

Ok, another thing you can try.. Are you sure the particles dont have any LOD's?

that might be the culprit.

How do I go about doing that please?

Wow thanks so so much for that Luos! That wasn't the problem unfortunately, and in a fit of rage I deleted the particle and redid it since it was so simple anyway. It now seems to be ok. So, who knows what the problem was... I guess I must have knocked a button or something?

Thanks for going above and beyond with your response though. So good of you.
