AmbientLight problems

[VeTaL]

Got a new strange problem: ambient light dont work in game (in editor it works good in both edit and game modes).

 

All other types of lightning works quite fine, except ambient. I made level from Underground models just to test animation hands in GUI, and stuck with this problem.

 

Also, i made search through all files in project (with Ctrl+Shift+F), where i mention "Ambient" and i find, that i didnt use it nowhere. Then i searched for text "Ambient" with Total commander searching tool and again found nothing strange.

Finally, i added AmbientLight(Vec3(1)); into the main loop and again there isnt ambient lightning on the scene at all (not only on mine, also on tunnels.sbx)

 

What can cause this?

I think i have missed something small, but i spend a all evening trying to fix this before writing here.

Things to try:

 

1. Is the ambient light in your project folder?
   
2. Are there multiple ambient lights? (perhaps causing interference)
   
3. Delete the ambient light in your editor and project folder and update your SDK.
   
4. Remove the ambient light from your scene and drag a new one in. Resave the scene as a different level and try to load that level.
   

 

good luck!

1. Of course, its all right in log file.

2. Nope, just one

3. Updating now.

4. Tried that, no results.

 

Also, i noted that i cant see any ambient light in any level in game, in editor its allright.

 

I'll try updated version now

You have the wrong Entities folder in your project.

[VeTaL]

Just deleted my Entities project folder and paste Entities from fresh 2.4 folder, add ambient light, set it to 0.3 + added player_info marker, because player placed here, and got still the same result: there is ambient light in Editor, but no in game.

[VeTaL]

I tried it on different maps: direct, spot and point lights work good in game, but not ambient.

[VeTaL]

Looking like this trouble is only in my current project: i added another simple project, load the same settings and the same map there and i see ambient light....

 

But i cant find any line of code, connected to ambients.

 

Strange indeed.

[Canardia]

You could temporarily rename the AmbientLight function in engine.cpp to make it cause compiler errors in places where you used the function.

Then you could find where you have used it.

[VeTaL]

I do that last night: no errors while recompile.

I also shut down HDR and all posteffects - result is the same.

 

Got an idea that this can be caused by CEGUI, because in other project, that used the same assets ambient is okay.

[VeTaL]

Its not CEGUI.

 

Just from desperate, change

RenderFramework(); 

to

SetBuffer(_buffer);
RenderWorld();

//Render lighting
SetBuffer(BackBuffer());
RenderLights(_buffer);

 

got a strange picture, but now i can see ambient. I'll test simple level with framework and ambient, maybe problem is there.

[VeTaL]

In simple demo with framework its okay with ambient... looking like i need to refactoring my project class by class and see, what happened.

[VeTaL]

Looking like its really Framework bug.

 

Can somebody else try this?

 

Initialize() ;
RegisterAbstractPath("../Assets/");
SetAppTitle( "Racing" ) ;
Graphics( 800, 600 ) ;
AFilter() ;
TFilter() ;


TBuffer gbuffer;
TCamera camera;
TMesh   mesh;
TLight  light;
TMesh   ground;
TMaterial material;


TFramework framework=CreateFramework();
TLayer layer = GetFrameworkLayer(0);
camera=GetLayerCamera(layer);

TEntity _scene = LoadScene("abstract::underground.sbx");

//PositionEntity(camera,Vec3(0,0,-2));

TEntity playerStart = FindChild(_scene,"playerstart_1");
PositionEntity(camera, EntityPosition(playerStart) + Vec3(0.0, 1.0, 0.0));

//Set Lua variable
BP L=GetLuaState();
lua_pushobject(L,framework);
lua_setglobal(L,"fw");
lua_pop(L,1);


// Game loop
while( !KeyHit() && !AppTerminate() )
{
	if( !AppSuspended() ) // We are not in focus!
	{

		// Update timing and world
		UpdateFramework();

		// Render
		RenderFramework();

		// Send to screen
		Flip(0) ;
	}
}

 

Its just standard template, underground.sbx is level with some tunnels, one point light and one ambient light.

When i tried with RenderWorld and so on - i saw ambient light and point light, but now i can see only point light.

 

Also, even when i add AmbientLight(Vec3(1)); before main loop, i also cannot see ambient.

So, looking like framework dont render world for ambients. (maybe this is not planned?)

[VeTaL]

Also, i tested

http://leadwerks.com/werkspace/index.php?/topic/381-scene-loading-example/page__p__5623#entry5623

but the result is the same: no ambient light, only spot.

[AggrorJorn]

does the scene contain a directional light? Perhaps they both need to be used in order to have proper ambient lights.

[VeTaL]

I need directional light to use ambient light? Strange indeed, because if i would have indoor level (like inside tunnels), i dont need directional light.

[VeTaL]

Anyway, when i use RenderWorld - UpdateWorld, i see ambient without direct light: my scene have only one source of ambient light and one source of point light.

[VeTaL]

Okay, i just added directional light, set it to 0 and now i can see ambient... It works, but i spend too many time to understand that ambient light need directional light.

 

PS: Aggror, thank you for idea about directional light.

[cassius]

There was an ambient light bug but it was fixed some weeks ago.Maybe a clean install is needed.

[AggrorJorn]

Well I didn't know it for sure either, but I remembered a topic were there was a problem with ambient lighting and a directional light bug.

Anyway, glad the issue is solved now.
