So no one knows how to do this? Should i try creating a lightmap of some sort to do this? Seems like a waste to me...
Anyone have any comments on this?

Well i don't think you need to reply in that manor.
But i have tried
Code: Select all
driver->setAmbientLight(video::SColorf(1.0f,1.0f,1.0f,0.01f));
and even with that it seems to be completely lit.
i can change it to say video::SColorf(1.0f,0.0f,0.0f,0.01f) and everything is red, so i'm a bit confused isn't the alpha channel used?
EDIT:
Alright i've gotten it working using:
Code: Select all
driver->setAmbientLight(video::SColorf(0.2f,0.2f,0.2f,0.2f));
I guess my problem came from a misunderstanding of the alpha channel.
Thank you to those who read this post geniuinly trying to actually help.
Have a great day.

Eh, apparently I came off in the wrong tone. I wasn't (trying) to be rude at all. It's just that a quick search for 'Ambient' in the documentation returned that function.

With ambient light the lightning of dynamic light doesn't react smooth. Is it possible to disable ambient light for just some models in the game?

I think that every object has an ambiant light value, so you could set it to default for whatever models you want to react normally. The API usually tells you the default value, that would be a good place to start.

SColor and SColorf use different initializations (concerning alpha):
SColorf(red, green, blue, alpha)
SColor(alpha, red, green, blue)
So it can be confusing...

Can't find anything to disable ambient light for one object

You can use something like this to disable ambient lighting for certain SceneNodes:
Code: Select all
IAnimatedMeshSceneNode *newNode;
.
.
.
for(int i = 0; i < newNode->getMaterialCount(); i++)
{
newNode->getMaterial(i).AmbientColor.set(0, 0, 0, 0);
}
