Lighting problems, what am I missing?

[Interrupt]

Things are progressing quite well in my project, but the lighting doesn't look like it should at all, the screenshots below show it. It looks like even though two models are right next to eachother, one gets lit and the other doesn't. My second problem is that none of the sprites I add get lit by lights, even if I set them to be.


Wrongly lit hallway, and sprite

More lighting errors

Is there something I can do to get Sprites to be lit by lights, and avoid the errors I'm having when lighting the models?

What are you using to make the scene?

BSP? If so what editor?

Billboards are 2D and thus have no normals, and no lighting information.

The scene is being made up of seperate models that are being added into a Static Geometry object.

I'm creating it like this:

Code: Select all

StaticGeometry* sMeshes = mSceneMgr->createStaticGeometry("DungeonBlock");
sMeshes->setRegionDimensions(Vector3(2500,2500,2500));
sMeshes->setOrigin(Vector3(0,0,0));

I add a model into it by attaching it into a Scene Node:
sMeshes->addSceneNode(thisSceneNode);

Making the lights:

Code: Select all

Light* pLight = mSceneMgr->createLight(lightName);
pLight->setType( Light::LT_POINT);
pLight->setAttenuation(900, 1.0, 0.00016, 0.00000012);
pLight->setDiffuseColour(ColourValue(0.9,0.6,0,1));

Maybe that will help things.
About Billboards, what would be the best way to light them? I'd like to light them dynamically, but I could compute their color by iterating through the lights near them if nothing else.

The lighting errors on your static geometry are likely to be caused by incorrect normals. Easiest way to prove this is to remove the static geometry influence for the moment and just add your blocks as entities - do they get lit the same way then?

About billboards - the simplest way would be to write a vertex shader which lights the billboard based on distance rather than vertex normal. Otherwise, you pretty much are limited to calculating it yourself in code, since no choice of normal will look quite right.
