How do i make my mesh all black?

[POi]

I have tried for a while now to set my mesh all black. I have set setMaterialFlag(video::EMF_LIGHTING, false) on the node and i have NO TEXTURE at the moment.
I also tried changing all the material colors (specular, ambient and so on) but for the love of it i cannot get it from all white to all black.
(I'm loading an .X model)

Do i have to change vertex colors? How do i do that ?

[POi]

I just realized i cannot do
node->getMaterial(0).AmbientColor.set
.... and so on when there is no texture ... but how do i change the vertex color ... the model is still all WHITE and i want it to be BLACK.

If you have no dynamic lights then you could do:

node->setMaterialFlag(video::EMF_LIGHTING, true);

to make the node all black.

Actually i want to have dyn. lights later on. So i would rather like to change the vertex col. from the beginning ... maybe i need to modify the engine ?

Can't you use textures? Why not trying a small plain black texture? This should fix this.

set the diffuse and emmisive colors to black. you can change the specular color to black for a pitch black model or to white for a black model with a white shine to it.

diffuse = the color the material emmits when struck by light
emmisive = the color the material emmits even without light
specular = the color the material emmits when hit by light at a certain angle to give your mesh a reflective look

all of these values are combined on a per-vertex level to calculate the effects of dynamic lighting. these values only work when EMF_LIGHTING is set to true.

Hmm, interesting. And what does ambient do then?

That is the website that taught me about lighting, it explains the different types of light well, including ambient light
