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"

some how i fix this problem on my particles, but standard "fire", disappear in Orthographic camera mode

Can you guys use the preview of the orthographic camera at all? Here it shows just the silhouette, although in game it works correctly. Even on Flappy Bird I get this behavior.

Hi everyone,

AFAIK the particle system shoulalt textd be visible (though probably difficult to see) in the orthographic viewports. I just attempted this with success: alt text

What version of the editor are you using?

I find I'm having the same issue using particles from UE4.3 sample project. Playing the game in orthographic shows no particles, however when I eject they appear fine. I am using the "Flame" particles, and the only particles appearing on the screen in Ortho are the spark particles.

Hi mmillwood,

Can you post screenshots of what you are seeing? I am having trouble reproducing this on my end and any clarification would help significantly.

Hi Adam, I'm seeing exactly what zip is showing in his video - fire particles show when detached and only spark particles in ortho (no flames or smoke). I have noticed, however, that deploying the game to device (Galaxy SIII) shows the particles correctly in orthographic mode. Seems to only be an issue with the editor (afaik).

I have the issue when playing the game. All cameras are fine except for when I switch to an orthographic camera where half my particles stop rendering (the particle effects which are 'firing').

It's 4.8.0-preview3 and still not fixed!

avatar image Adam Davis STAFF May 28 '15 at 02:57 PM

Hi cailei,

Unfortunately this has not been fixed as of yet. Our resources are currently allocated elsewhere. I have updated the bug report to reflect that additional developers are experiencing this error.

Hi, I've been keeping my eye on this thread and was wondering if there had been any updates or a time frame for fixing this?

Does anyone have a temporary workaround? I can't see how anyone is making any 2d games that have particle effects with this issue.

avatar image Adam Davis STAFF Sep 26 '14 at 04:50 PM

Hi Balka,

This is still under assessment by the development staff. Unfortunately, I do not have an adequate timeframe to give you on when this will be fixed.

avatar image Dredok Feb 01 '15 at 12:12 PM

is this already fixed? any ETA?

avatar image Adam Davis STAFF Feb 02 '15 at 05:10 PM

Hi Dredok,

Unfortunately this has not been fixed as of yet, it is still being assessed by the development staff.

Any insight? :D

Hi paragonx9,

Unfortunately I do not have a timeframe of when this will be fixed. Keep an eye out for our release notes on future updates!

As a temporary fix following worked for me: open sprite material (eg fire, smoke or whatever) and change the DepthFade-value to zero. Unfortunately it's not a proper solution, but in my case it's better than nothing. Hope it helps.

(I added a param for DepthFade-value, so I am able to change it on the fly, depending on my camera mode).

avatar image Rotlaust Jul 04 '17 at 08:54 AM

Awesome, this did it for me! Been scratching my head about this one for weeks, remade my sprites several times and a slew of other things trying to figure it out. Thanks a ton.
