Questions on Lightmapping

[PapillonFH]

Hey there!
I'm creating a new for tournament use, and I face some issues with the lightmapping.
Situation:
I did terrain lightmapping (medium) with the following settings:
- sun low over the horizon, early morning.
TerrainLight.con

Code: [Select]

rem ******** Lightmap Generation Settings ********
if v_arg1 == BF2Editor

LightMapGeneration.init
LightMapGeneration.GILightsBaseDir 0/0.33/-0.66
LightMapGeneration.GILightsIntensity 0.33

LightMapGeneration.skyWhite 0.3
LightMapGeneration.numberOfGILights 8
LightMapGeneration.sunLightShadowIntensity 1
LightMapGeneration.sunLightFov 2
LightMapGeneration.sunLightIntensity 1

endIf

The effect is good so far, see screenshot.

Basic question: Why are buildings/statics "lightmapped" when I do terrain lightmapping?

But now:
I lightmap a building with the following settings:

ObjectLight.con

Code: [Select]

rem ******** Lightmap Generation Settings ********
if v_arg1 == BF2Editor

LightMapGeneration.init
LightMapGeneration.GILightsBaseDir 0/0.33/-0.66
LightMapGeneration.GILightsIntensity 0.5
LightMapGeneration.GILightsShadowIntensity 1
LightMapGeneration.GILightsFov 45
LightMapGeneration.UseGITopLight 1
LightMapGeneration.GITopLightIntensity 0.1
LightMapGeneration.GILightsViewDistance 10
LightMapGeneration.skyWhite 0.5
LightMapGeneration.numberOfGILights 8
LightMapGeneration.sunLightShadowIntensity 1
LightMapGeneration.sunLightFov 2
LightMapGeneration.sunLightIntensity 3

endIf
..the result is not what I expected.
What is lost is the sunlight on the house front that was there after the terrain lightmapping, see house in the center:


1. What am I doing wrong? Or am I understanding something probably completly wrong?
2. Shall I even do more lightmapping? I think the buildings look good even w/o object lightmapping.

Any help is appreciated :-)

I tried to follow those tuts here:
http://www.bfeditor.org/forums/index.php?showtopic=10002
http://www.bfeditor.org/forums/index.php?showtopic=10002
and the standard tut from Fenring, but I seem to miss essential basics :-(

Doesn't look like the statics are lightmapped at all in the first screenshots.

[PapillonFH]

That's right, 1st screenshot is after terrain lightmapping.

[gavrant]

I concur with Ts4EVER, it looks like both screenshots are missing terrain and statics lightmapping - no shadows on the ground from the building and wooden pallets, buildings interiors are too bright, windows and doors are sunlit despite being on the dark side. With your terrain lighting settings (specifically, LightMapGeneration.GILightsIntensity 0.33 and LightMapGeneration.GITopLightIntensity 0.1) I would at least expect aggressive shadows on the ground.

BTW, did you install FH2 lightmapping samples? Asking because the tutorial from the first post obviously doesn't mention that part.

[PapillonFH]

Yeah, are installed. Unzipped fh2-samples-2.5.776.zip is here:
C:\Program Files\EA GAMES\Battlefield 2\bf2editor\objects

What I did was to lightmap the primary terrain on medium quality AND I object lightmapped that one building that now is very dark..

Can someone tell me in a few sentences:
Terrain Lightmapping will do the following:
Object Lightmapping will do the following:

[gavrant]

Yeah, are installed. Unzipped fh2-samples-2.5.776.zip is here:
C:\Program Files\EA GAMES\Battlefield 2\bf2editor\objects

Mine were unpacked straight to ...\Battlefield 2\mods\fh2 (the zip has the Objects folder inside).

What I did was to lightmap the primary terrain on medium quality...

Try to lightmap the secondary terrain too?

... AND I object lightmapped that one building that now is very dark..

Sorry, skipped the "see house in the center" part. Anyway, I'd try to lightmap one of the front buildings instead, as that house may be obscured from the sunlight by other buildings.

One note: when you relightmap any static, restart the editor to see new lighting. The editor shows new lighting without restart only if the objects has not been previously lightmapped, at least in my case.

[Mudzin]

Actually what does "secondary terrain" mean? Is it the terrain around the map or does it mean more detailed lightmapping of primary terrain?

[PapillonFH]

Secondary Terrain is not yet done.
Actually I set a building just on top of that mountain in kp9 where one can even see the sun painting the surface, but that stayed dark too.
Yes, the objects folder comes from the zip.

[Ts4EVER]

Static lightmaps often turn out a tad darker than expected, just tweak the lighting settings a bit (object lighting)

[PapillonFH]

Can you gimme some hints on what setting will change what?
I have this explanation here, but I'm not sure about the value range of most of those settings:
