Really Dark Lighting

[vroomhenderson]

So, all of my models are really dark. The sky is supposed to be a darker color, but I'd like to add some light to the maze so that people can actually see what they're navigating. Here's an image of what it looks like currently:


As you can see, the models are visible, but can't be navigated without turning my screen brightness up to full. Here's what I've tried to solve the problem:

• Adding a point light.
  Changing the ambient lighting (but it's already at the max).
  Disabling lighting for the maze node.
  Disabling stencil buffers.

I have Irrlicht running in OpenGL mode. I can post my code as needed. I've been stuck on this issue for a week or so and have gotten nowhere.

Thank you!

Are irr examples also like that? If so, update your drivers.

[vroomhenderson]

The compiled irr examples look good. My drivers are up to date.

It looks like a problem with your models. Your UVs look baa in any case, but this wouldn't account for the darkness. Check that your materials have diffuse set to white and maybe that the vertex colours are white.

[vroomhenderson]

Yeah... I really need to work on the UVs, but I need to actually be able to see the model first! I tried setting the material diffuse to white, but there was no effect. I'm not sure how to set the vertex colors.

I got point lights to work (but they're still pretty dim at full brightness.) Ambient lighting is even dimmer.

Code for ambient lighting:

Code: Select all

device->getSceneManager()->setAmbientLight(video::SColor(255,255,255,255));

Code for material diffuse:

Code: Select all

this->object->getMaterial(0).DiffuseColor.set(255,255,255,255);

Thank you for the help! I know this must sound pretty trivial.

I think you have to set the ambient colour on the material as well. They are probably multiplied together.

[vroomhenderson]

Yep! That fixed the ambient lighting! Point lighting is still quite dim. Is there something that I might be forgetting to set with that? I can see the lighting effect with the point lighting, but even at full brightness, it's hard to see with ambient lighting off.

Did you follow the advice in the header regarding radius and attenuation?
