Corona
A corona is created by making a light that has a skin associated with it. It is often erroneously called lens flare).
UT
Here are the steps for making a corona in UT:
- Place a Light (UT) wherever you want the corona to appear.
- Open the Texture Browser and select a corona texture. There are some nice ones in GenFX and City.
- Open the Actor Properties for the light. Set the following properties:
| Group | Property | Value | Explanation |
| Display | Skin | Click Use to give your light the texture you just picked out. | |
| Display | DrawScale | 0.1...0.3 | Scales the corona image; with 1.0 it's rather large. One unfortunate consequence of this is that this property also scales the actor icon in UnrealEd, making corona actors hard to find. |
| LightColor | Brightness | 0.0 | Set so that your corona won't also cast light. You'll need to use a second light for that. |
| LightColor | LightHue | Set a colour for your corona (if you are using a white skin that is, if you have a colored one then just leave it). | |
| Lighting | bCorona | True | bLensFlare was used with Unreal1 and is obsolete in UnrealTournament. |
| Lighting | LightRadius | anything | sets how far the corona will be visible in game |
The map must be rebuilt (including geometry) to see the effect.
Caveats
- Coronas can only be seen through masked semisolid or nonsolid brush.
- A corona textured light can also be used as a light emitting source, but the corona will only be seen in game as far as the radius is set.
- To make a small radius light seen from afar, use 2 lights. Set the corona textured light actor brightness → 0.
Viewing Coronas in UnrealEd
(Could someone confirm which rendering modes display them in UnrealEd?)
- Type camera open into the UnrealEd Console
- Maximize the floating viewport
- The viewort should use accelerated rendering and show lens flares.
- Press Alt+Tab to return to UnrealEd.
Caveats
Birelli: Software rendering in UED does not display coronas as D3D does. As for looking at it in the editor I always just right-click the top bar of my 3-D viewport and go down to D3D, I'm not sure what this camera open thing does though, maybe it's better
Tarquin: "Camera Open" opens a floating viewport you can maximize to the entire screen. It's good for people with a dinosauresque 2-card setup who can only run OpenGL fullscreen (like me)
Comments
Tarquin: Do we need to update this for UT2003?
MythOpus: I think So. Unfornately, I haven't mapping lately to see whats changed...
