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"

Shadows not working in Orthographic

This is a continuation of the forum post i wrote for Tim Hobson: https://forums.unrealengine.com/showthread.php?54610-Unreal-Engine-4-7-Preview&p=227189&viewfull=1#post227189

Relevant info:

  • My game is simply barebones at the moment, no complex logic with regard to rendering.

  • My Directional light source is set to Moveable. Tried Static and Stationary as well.

  • Tried turning on and off many settings in the light source

  • My camera is connected by a spring arm to a movable sphere, hooked up to wsad (It's an RTS game).

  • I'm on SM5.0

  • Shadows work perfect in perspective mode.

  • Engine scalability set to Epic (I'm on a gtx 980).

  • point light works perfect. So does spot light

Thats about all the information i can think of. Let me know if you find anything Tim Hobson. Thanks

Hey Makotech222,

I've gone ahead and assigned myself and moved this over to Bug Reports to see if we can try and track down what's going on. I'll take a look at this as soon as I can. :)

Hey Makotech222,

I'm still looking into this one for you, but could you update to the final release of 4.7 that came out today and let me know?

Thanks!

Makotech222 gravatar image Makotech222 Feb 25 '15 at 12:42 AM

Just updated the engine and tried it out. Still have the same issue. Tried lighting quality on High instead of preview and that didn't help either. Are you seeing the same issue as I am?

Hi Makotech222,

I've reported this issue with UE-11026. When I tested this I tested with 4.6, 4.7, and our internal build of what will become 4.8. This was happening in all three and is not isolated to being an issue directly related to 4.7. I was able to see that using stationary lights cause clipping artifacts. If the directional was made to be movable from stationary it would lose all shadows. When going back to stationary these shadows would remain removed until lighting was rebuilt.

Here is the video of my results with testing in 4.6: https://www.dropbox.com/s/sf0z5k8vdnzdx3g/OrthographicShadows.mp4?dl=0

Thanks again for reporting and I will update once the ticket has been resolved, however there is no ETA for when this will be assessed by an engineer.

Tim

Very interesting results. Thanks for following up. I don't mind waiting for a fix, as long as it's in the queue I'll be happy.

has there been any progress on this, because i think we are seeing the same behavior in our game on 4.9.2

Tim Hobson gravatar image Tim Hobson ♦♦ STAFF Dec 02 '15 at 06:21 PM

This ticket is currently backlogged at the moment. I know it gets old hearing, but once a fix has been submitted I will be able to post back here with more details and a release of the engine that this will be included in. Unfortunately there are only a limited number of developers vs the bugs that have to be prioritized.

I did just try this in our what will be our 4.11 build and I'm not seeing an issue like before though. While that doesn't mean it is fixed, maybe it's improved there.

Im on the 4.11 preview and this is my downwards facing camera in orthographic view. As you can see there are only shadows on one part of the screen, any tips on why?

Tim Hobson gravatar image Tim Hobson ♦♦ STAFF Feb 08 '16 at 10:01 PM

It's still part of the same issue. It's dependent on the view angle. For instance, using the Third Person template the shadow doesn't work at regular view angles for third person, but adjusting the camera to be overhead will allow the shadow to be visible.

This is ticket is still backlogged at the moment though.

Its 4.11.1, still this problem exist. If this problem persists after next patch/update, i am switching to Unity. Frustrated by the orthographic camera.

desert_racer gravatar image desert_racer Jul 14 '16 at 10:56 AM

Are there any updates on this?

Tim Hobson gravatar image Tim Hobson ♦♦ STAFF Jul 14 '16 at 11:37 AM

@desert_racer

It's still marked as backlogged, so no update at this time really.

Here is comparison of unity's orthographic camera + directional light vs UE4 (4.11.1). Epic is just a pathetic company, half engine, full frustration over lighting and shadow.

Please, go there and vote, so Epic can know how important this is for us.

Also have this bug. This is extremely important for my project! :(

Using 4.13.1 and shadows are still not visible through orthographic cameras. You can almost get around this issue by using a perspective camera with a very small FOV and then moving the camera very far away to see enough of your scene. Are there any better workarounds?

LordDMasters gravatar image LordDMasters Oct 24 '16 at 04:28 PM

HI there, Im in the same situation, I tried the same solution than vle07 but its not what i want, I hope in 4.14 they fix that

Tim Hobson gravatar image Tim Hobson ♦♦ STAFF Oct 24 '16 at 06:10 PM

@LordDMasters

Currently not planned to be added to 4.14. It's backlogged at the moment and I'm not aware of any significant work planned for the Orthographic view it may be a while yet before this is fixed. With full source availability, you do have the option to implement the fixes yourself as well.

Why all the 52 votes that issue had has been reset?

Piranhi gravatar image Piranhi Jan 19 '17 at 08:05 PM

I could really do with a fix for this as well. Voted, but @Tim, do you know if anyone is looking at this yet?

Cheers, Chris

@Piranhi

https://issues.unrealengine.com/issue/UE-11026

Sorry Chris, but the issue is still backlogged. Maybe one day. The reality, also is, that not all features/bug will be added or fixed by Epic. With source availability, we do leave open the option for teams to resolve some of these on their own projects as needed. Unfortunately, not every bug or feature will be addressed by Epic.

Piranhi gravatar image Piranhi Jan 20 '17 at 03:27 PM

@Tim I completely understand, no problem :) - I've voted for it anyway, so we'll see.

Unfortunately it's not the kind of thing we can fix as we don't have a programmer (there's only two of us). We'll come up with a work around for now.
