White Textures

I know I saw this problem here before, but I can't seem to find it now. Only recently I upgraded Irrlicht to the latest version, and my last build worked (displaying heightmap, adding textures, etc), however, now when I compile with the latest version, all the textures are white? I was wondering what causes this and most obvious, how to fix it.
Heres the world creation code, I took out the irrelevant parts, I think it should be easy enough to figure out.
Code: Select all
void WORLD::createWorld(const c8 * heightmap, const c8 * texture, const c8 * detail)
{
...
terrain = device->getTerrain(heightmap);
// smgr->addTerrainSceneNode(...);
terrain->setScale(vector3df(500, 7.0f, 500));
terrain->setMaterialFlag(EMF_LIGHTING, false);
terrain->setMaterialTexture(0, device->getTexture(texture));
terrain->setMaterialTexture(1, device->getTexture(detail));
terrain->setMaterialType(EMT_DETAIL_MAP);
terrain->scaleTexture(1.0f, 40.0f);
terrain->setMaterialFlag(EMF_FOG_ENABLE, true);
device->getDriver()->setFog(SColor(100, 200, 200, 225), true, 50.0f, 40000.0f, 0.01f, false, false);
device->getSceneManager()->addSkyDomeSceneNode(device->getTexture("resources/texture/sky.jpg"), 50, 50, 1, 1);
device->log("World Created\n");
};

Alright well, I hate to "bump" topics but this is really frustrating now. I completely rewrote my wrapper, only to find out draw2DImage(ITexture *, ...) only draws a white image - when the image is clearly colored (png, 512x512).
The image loads fine acording to the console, and I can see where its positioned, the catch is that its completely white.
Code: Select all
// loading image code
tex = driver->getTexture("resources/texture/tex.png");
Code: Select all
//drawing image code
driver->draw2DImage(tex, position2d<s32>((800/2)-(512/2), (600/2)-(512/2)), rect<s32>(0, 0, 512, 512), 0, SColor(255, 255, 255, 255));
Now, I've noticed that changing the SColor R,G,B values change the image's (or I guess I could call it a filled box <_<) color - which I get, but why isn't it displaying the texture?!?
You'd think this would be a simple mistake, but so far I can't find anything to fix it.

Hey
Are you compiling your code as it originally was, or maybe possible you added or modified it somewhere.
My first point of call would be looking somewhere at the lighting
Maybe you added something new, or changed the intesity of a light.
Just a guess, but that's where I would start

None of the above really
- it was perfect before, but
when I upgraded
to the latest version of Irrlicht (without any changes to code), all textures started comming in white (both terrain and 2d image). Thanks for your input though.

What are your system specs (OS, driver, card)? Also I don't think that lighting is a problem because this is 2DImage.

Which Irrlicht device do you use? Do the binary examples of Irrlicht SDK work for you?

Code: Select all
// device
device = createDevice(EDT_OPENGL, dimension2d<s32>(x, y), 16, fullscreen, false, false);
// texture creation flag, turned this on and off but doesn't change anything
driver->setTextureCreationFlag(ETCF_ALWAYS_32_BIT, true);
And nope, examples work but no textures (or images), the GUI is only partially visable too.

Hmm, probably an init problem. There exists a glxinfo equivalent for windows which prints out all supported extensions and some interesting information of your OpenGL installation. Please send me the output.
Also try DirectX device which might be quite different from what is used or supported.

OpenGL driver version check (Current: 6.14.10.3889, Latest known: 1.2):
Latest version of display drivers found
According the database, you are running the latest display drivers for your video card.
Compiled vertex array support
This feature improves OpenGL performance by using video memory to cache transformed vertices.
No paletted texture support
This may cause performance loss in some older applications.
Multitexture support
This feature accelerates complex rendering such as lightmaps or environment mapping.
Secondary color support
This feature provides an alternate method of coloring specular highlights on polygons.
No S3TC compression support
This may cause performance loss in some applications.
No texture edge clamp support
This feature adds clamping control to edge texel filtering. Some programs may not render textures correctly (black line on borders.)
No vertex program support
This feature enables vertex programming (equivalent to DX8 Vertex Shader.) Some current or future OpenGL programs may require this feature.
No fragment program support
This feature enables per pixel programming (equivalent to DX9 Pixel Shader.) Some current or future OpenGL programs may require this feature.
No OpenGL Shading Language support
This may break compatibility for applications using per pixel shading.
No Frame buffer object support
This may break compatibility for applications using render to texture functions.
Few texture units found
This may slow down some applications using fragment programs or extensive texture mapping.

And DirectX doesn't work (I'm under the impression its because gnu-gcc/codeblocks; gcc library says "DIRECT3D[version] Not Compiled in this Library... etc, etc - and don't have VS installed at the moment).

Since I can't find a solution I'm just going to downgrade back to 1.1 since I'd hate to scratch this wrapper now that I got FMOD's undocumented C API to wrap with it. Its ashame really, I was looking forward to the new improvements.

The examples are compiled with MSVC so you can test DirectX using the examples. And did you check for driver updates?

Yea, the DirectX version in the examples don't work either, and I've got the latest driver updates.

Argh, one last thing before I throw Irrlicht out the window, now that I've downgraded back to 1.1, it doesn't want to create the device, before device creation the console says...
Multittexturing active
Then its crashed with a Windows Error Report. What I'd really like to know out of all this is why its saying, 'Multittexturing active', why is it crashing right before (or at) device creation, and why's multitexturing spelt wrong?
