UnrealEditor FAQ - UnrealEditor 3
This FAQ (Frequently Asked Questions) is divided into three parts. One is for Unreal Editor 2, another is Game Related and the last one is the one you're currently viewing.
Note: If you're having trouble with UED 3 and you don't find a solution in this section, you might also want to check out the UED 2 section. A lot of the problems/solutions presented there still apply to UED 3 (such as the infamous "white viewport problem").

I'm running Windows 98 and UnrealED doesn't run. |
| Download and install the latest official patch. Even if you have the patch installed, UnrealED 3 might act weird or crash regularly on Windows 98. UnrealED 3 was programmed to be run on Windows 2000 or Windows XP, it wasn't programmed to be run on Windows 98. |
UnrealED seems to have a bug when I rebuild AI-paths. |
| Download and install the latest official patch. |
Mathematical Expressions in builder properties. |
| This feature has changed in Unreal Editor 3. Now, you can simply type in your expressions, there is no = sign necessary. So for example typing in 256*4 as height will result in the height of the brush being 1024 once you press the "Build" button. UED3 will not calculate the result once you press enter (as in UED 2). The expression will remain displayed, even when you press "Build". Closing the brush builder properties and re-opening it will display a single number again, namely the calculated value. |
Measuring Staff. |
| Hold SHIFT, press the wheel-button (middle mouse button) and
drag the mouse. A line will be drawn and the distance of that line will be displayed. |
Freehand Polygon Drawing Mode - Quick Reference. |
| Activate this mode by clicking the appropriate button in the left toolbar. Once it's activated you can start placing the vertices of your polygon in the viewport of your choice. To add a vertex hold down CTRL and right-click with the mouse on the spot where you want the vertex to be. You don't have to close the polygon because UnrealED will automatically connect the last vertex you placed with the first one you placed, once you make the brush. When you have the shape you want the brush to be, simply right-click somewhere in the viewport and click on "Create Brush". UnrealED will ask you how deep the brush must be. Enter a value and hit OK. Now the red builder brush should be there in the shape of your polygon and with the depth you filled in. I did notice that complex polygons have a tendency to screw things up. |
Lock to Selected Actor. |
| Locking to selected Actor is very usefull when you're doing things like getting a spotlight to shine right where you want it. The easiest way to use it is like this. In your 3D-preview viewport click on the "Lock to Selected Actor" button (it's right next to the "Large Vertices"-button). Now select your spotlight. You'll notice that the camera instantly changes location and rotation to match the location and rotation of the spotlight. Now simple move/look around in this viewport as you normally would and you'll see that the spotlight moves/rotates along with you. |
Align Cameras. |
| Do you have problems finding actors in certain viewports? Then this might help you. Right-click with the mouse on the actor you need and click on "Align Cameras". This will align all the viewport's camera's to that actor's location. You might need to activate a certain viewport before it jumps to that location, unless Realtime Preview is enabled. |
Usefull Shortcuts. |
| There is a whole list of new shortcuts in UnrealED 3.0. Here are some of them. These works when a viewport is active and will change what it displayed in that viewport.
These works when you are selecting surfaces on brush.
These work when you are working with the Red Builder Brush.
Note: This is in no way a full list of all shortcuts. If you want a full list of all possible shortcuts, you can find it here. |
How do I spy on bots (for when I'm working on my Botpath-Network)? |
| It depends on which version of UT2003 you have. If you have a version older then the 2186 version then it's pretty hard. But if you have the 2186 version or later, then it's easy. Two usefull commands to get information on what the bots are thinking are "showai" and "showdebug". These work in all versions of the game. Version older then 2186: Version 2186 and later: |
My skybox doesn't show up in multiplayer matches, how come? |
| This is a known issue, apparantly you need to add a zone-info actor in each zone where you want the sky to show up. |
Where can I find the CTF-Flags in the Actor-tree? |
| They are found pretty deep in the Actor-tree. So open up the Actor-browser and go here:
Here you'll find both the Blue and Red CTF-Flags. |
How do I make my DM/CTF/BR/DOM Level an actual DM/CTF/BR/DOM level? |
| Apart from adding the necessary actors (for example CTF-Flags in a CTF-level) there are two things you need to do. DefaultGameType:
Filename:
|
Most of the LightTypes/LightEffects don't work. How come? |
| This is a known "issue". In Unreal Tournament using these LightTypes/LightEffects usually meant that the lights would become dynamic. Dynamic lights slow down the level a lot, so they took most of them out of Unreal Tournament 2003. But don't worry you can get those effects in other ways. UED 3 supports Projectors and Emitters. With these two you can create the lighteffects you want. Projectors can be used for example if you have water somewhere and you want the water to shimmer on the walls. Check out "DM-Curse3", "Projector1" is an example of this. But for other effects you might need to use an Emitter. For example a flashing light can be done with an Emitter. Check out "CTF-Maul", "xEmitter6" is an example of this. However, some LightTypes/LightEffects still work. You need to add an Emitter-actor instead of a Light-actor. In the Emitter-actor's properties you can just adjust the light settings and choose a lighteffect that you want. Of course the emitter doesn't need to emit anything. |
I don't see the grid in the 2D-Editor! What's wrong?
|
| By default UED 3 starts up with quite high brightness, contrast and gamma settings. This causes the grid to "disappear" in the 2D-Editor. It is there, but due to these high settings you cannot see it. To see it you can do this:
Note: When you change a value and go to the next one, the old value will re-appear! The value is changed however, it just displays the old one again. If you close the "Advanced Options" and open it again, the new values will appear. There is another way to solve this problem. Make a shortcut to UED 3 on your desktop for example. Right-click it and goto properties. In the target-textbox there will be something like this: "C:\UT2003\System\UnrealEd.exe". Add -nogamma at the end of it, so it reads: "C:\UT2003\System\UnrealEd.exe -nogamma". Hit OK. Now when UED 3 starts the screen should remain at it's normal brightness level. |
The editor crashes when I try to dock/undock browsers! |
| This is a known bug. There is nothing you can do about it. On some systems it works, but on most systems it doesn't work. Just leave the browsers as they are. |
How do I make Translucent Textures? |
| Here is a quick how-to:
That should do it. |
I can't select surfaces or other things! How come? |
| If you have trouble selecting things you might want to try turning down or disabling "anti-aliasing" of your video-card. How you turn it down or disable it really depends on what video-card you have. The "anti-aliasing" settings are usually found here:
|
I get an error 'Brush x: has null material references', what does it mean and what do I do about it? |
| If you get such errors, this means that Brush x hasn't been textured yet and still has the default (ugly) bubble texture. It's actually just a warning, you can leave it as it is, though that texture looks ugly ingame. |
How do I make panning textures? |
| The easiest way is making a new texture. So start a new texture. Type in the name of the package (and group if you want) and name of the new texture. Make sure the "MaterialClass" is set to "TexPanner". Click "OK". In the Texture Editing-window you get next, you simply need to adjust the setting "Material". This needs to point to the texture you want to pan. With the other settings you can adjust the speed of panning, direction,... If you made the new texture in a package other then "mylevel", then make sure you save the texture-package! |
Movers appear at a wrong location in online games. How do I solve this? (Thanks to 'Angel_Mapper') |
| If they appear at the wrong location, they'll most likely appear at the origin of the Unreal-world. If it's just a normal rotating mover that you don't want the player to be able to affect in any way, set it's "bFixedRotDir" to "True" and give it a "RotationRate" as you would normally, but here is the difference: instead of setting it's "Object" -> "Initial State" to "RotatingMover", use "TriggerOpenTimed" instead. This ensures that the player bumping into it won't make the mover go crazy, but avoids the apparently broken "RotatingMover" property. |
How do I add a WeatherEffect to my map? |
| We'll be covering Rain in this quick tutorial, but other WeatherEffects are achieved in similar fashion. Open the actor-browser. Near the bottom of the list there is an actor called "xWeatherEffect". Select it and add it to your level. It's location doesn't really matter, although it might be a good idea to add it in an sky area (but not in the skybox). Next thing you need to do, is give the actor a texture/skin to work with. To do this, open the xWeatherEffect's properties and goto Display->Skins. Click "add". Now open your texture-browser and load in the texturepackage "EmitterTextures". Once loaded goto the group "MultiFrame" of this package. There should be a rain texture there ("RainFB"). Select it, go back to the xWeatherEffect's properties and click "use" next to the newly added skin. Ok, we're almost there. Now there are some other properties we'd like to set. These are under "xWeatherEffect". This list is not exhaustive and you can play around with all properties to get your xWeatherEffect "just" right.
There you go, this should give you a nice rain effect. |
When I export textures, they are in a weird format (.dds) which I can't get open. What do I do? |
| This is actually the standard format in which they are exported now. There are two possible solutions, depending on your preference. The first solution is getting a plugin so your graphics program (Photoshop or similar) can open DDS. You can find DDS tools here. The second solution is downloading this. This will allow you to export textures to tga-format, which is a more common format. I uploaded this little utility to my site as I don't know anymore where I found this. Credits go to whomever made it. |
My terrain disappeared all of the sudden! What's going on? |
| This is known to happen if you substract a cube. Doing a full rebuild should fix the problem. |
How do I make an animated preview screenshot-sequence for my level? |
| There is a nice tutorial covering this right here. |
When I click the texture-browser button nothing appears? Same goes for other browsers. |
| There might be several causes of this.
|
How do I add Weapons in UED 3 (for UT2003)? |
| The way weapons are added in a level for UT2003 has changed, compared to UT1. Now you don't add the weapon itself, but rather a weaponBase that will contain the weapon of your choice. Open your Actor browser and find the actor "xWeaponBase" in the "xPickUpBase" section. Add this actor where you want the weapon to appear in your level. Once placed, open the properties of that newly added "xWeaponBase". Goto the "xWeaponBase" section and select the weapon of your choice in the "WeaponType" dropdown box and you're set. |
