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"

Moving Particle emitters, particle flicker/overlapping

Cant really explain it better than that.. I created a particle system and used 5 of them to rotate around the player. As long as the particle systems arent moving (trough blueprint) they behave as expected. No particles in the background try to compete with the ones in front of them. but as soon as the emitter itself starts moving.. particles in the background will start "fighting" with the ones in the foreground.

I have tried all the sorting options, none are any help lessening this problem. I tried playing with tranlucency passes, temporal AA and the likes.. nothing.

Any suggestions on how to make them particles not clip/fight/flicker on top of eachother is appreciated.

hmm, (dynamic) transparancy priority sorting seems to fix it. Problem solved!

Hello guys I've just had same problem. I fixed it by UNCHECKING "separate transucency" in material properties of my particle material.

How did you set your transparency priority sorting to be dynamic? I have a similar problem going on right now.

I cant remember exactly, as its been a while. Actual dynamic priority sorting wasnt working, we set up this massive elaborate blueprint that sorts multiple emitters depending on camera distance.. but when one of the emitters suddenly move behind another, you can see the particles swap sorting places.

One way to solve it is to have all the particle effects in the same emitter, which sometimes can be tedious. another way is by setting the sorting order in blueprint.

When I have a little more time, Ill screenshot some stuff for you.

Roger. Right now I just hijacked mine manually, kind of like you explained it. I think I'll put it all in one emitter and give that a shot and see if its any smoother.

Thanks for the reply.
