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"

Landscape proxy (Visibility holes & splines)

Hello everybody,

I currently work with the Landscape tool combined with Level streaming, I noticed some missing functions or maybe bugs. Thats why I want to share them with you and I hope that these bugs get fixed in the future, because these problems are a big problem in my current workflow and in Level Design. If these aren't bugs I hope for some answers, which help me out there. :-)

  • I created a Landscape proxy, on which I can't add splines (I tried to press ctrl and clicked on the landscape like I normally add splines). It seems like that splines only work on a normal Landscape and not on a Landscape proxy, would be great if you could fix this or give me some advice how to get it to work.

  • I can't create holes/visibility holes into the Landscape proxy, which makes it hard to create tunels in the Landscape proxy.

  • I also noticed some time ago, that I can't create small visibility holes in the landscapes. I can only cut off landscape component squares in the terrain, which is not that good for creating tunels and these stuff like it was in UDK.

These are the things I currently noticed with Landscape proxys and I hope they get fixed in the future, or I get some advice because of these problems. Because these problems making it very difficult to work on my Landscape. :-(

If you need some more details, feel free to comment and I will reply to it!

PS: Sorry for my English.

best regards

Hi frezer748,

Can you tell me what steps you are taking to create your proxy landscape? That will help me to reproduce your bugs. Thank you!

Thanks for the reply! Sure I can tell you how I did the landscape proxy.

  1. I created a normal Landscape and edit the Landscape (added some mountains in there).

  2. I click on the "Selection tool" under "Manage" in the Landscape tools. And clicked on the landscape squares I want to have as another Landscape (Landscape proxy) for Level Streaming .

  3. I clicked on the Landscape parts I selected with the tool (I click on them with still having the selection tool of the landscapes) so I get a yellow border around the selected Landscape parts and went into the Levels tool where I have an overview of the maps I imported into the scene.

  4. I made a right click on the Level List and clicked on "Add Level>Add Selected Actors to a new Level". Than I saved the selected Landscape parts as a new map.

  5. Last I did was that I selected the Persistent Level (in this case) and clicked on the Landscape tools again, I clicked on "Manage>Move Level", and clicked again on the the Landscape parts I want to get cut off, and than I clicked on the new Map in the Level List and pressed "Crtl" so that the Landscape parts get moved to the other Map.

And that should be it, after the last step I selected the new Map in the Levels List and tried to add Splines or create visibility holes on the Landscape proxy, but it doesn't work. I can't create visibility holes in the new Map(Landscape proxy) and I can't attach Spline lines to a specific map. I can only add the Splines to the persistent Level.

I hope you understand my steps. If you have any questions or problems with one of these steps than just write in this post, and I will answer it as soon as possible. Thanks for helping out and I hope this bug may get fixed maybe even in the next patch (4.2). :)

Hi frezer,

Unfortunately I have been unable thus far to replicate your results. When I moved the landscape level into a level other than persistent I was still able to place splines. Further, how is your visibility mask set up for your landscape? Can you post a screenshot? Thank you!

http://i.imgur.com/IQ1Nfrj.jpg I made a screenshot of the landscape hole material. Well it seems like that you can add Splines, but it attach the Splines always on the Persistent Level, and if you hide the new Created level in the Levels List than the Splines don't disappear which is not that good for level streaming, sometimes I also can't attach the Splines on the Landscape proxy which is pretty weird. And because of the Visibility holes I can only create them in the normal Landscape but it doesn't work in the Landscape proxy.

best regards

Hi frezer,

Are you making sure to set the level with your landscapes as the current level? I noticed that visibility and splines won't properly work if the sub-level with your landscape in it is the one selected as current. Otherwise I have not been able to reproduce this effect. Both the splines and the holes seem to work as intended.

Thanks for the answer. Well yeah I'm sure that I set the Map where the Landscape proxy is in, to the current level. But it still doesn't allow me to draw some holes in there. Same with Splines, it seems like that the Splines can't be added to the Level where the Landscape Proxy is in. I tried to make the Landscape Proxy level invisible but the splines are still exist, so the splines seems only be able to add in the Persistent Level. I will try to make tomorrow maybe a video or a screenshot gallery of my workflow so I can also show it to you what I do.

best regards

Hi frezer,

This is a known issue with landscape visibility. If you put the landscape visibility mask in your original landscape material instead of a separate one, this should no longer occur. Thank you!

I just read it in the patch notes for 4.2 and tested it now in the unreal engine 4 (4.2) and I see you guys really fixed these two problems. I'm so thankful for this fix, it makes things so much easier now! Thank you so much for this fix, you guys are incredible awesome!

Edit: I just noticed a very small bug still with the visibility hole on a Landscape proxy :(


I painted a little hole in the Landscape proxy, but the texture around the area are getting deleted (it's getting a black texture), and I can't redraw them otherwise the visibility holes disappear again. When on a landscape proxy aren't any holes anymore than the textures getting automaticly back.

best regards
