Вот мой код загрузки: 

GLuint Utils::loadTextureRAW(const char *filename, int width, int height) {
GLuint texture;
char *data;
fstream file(filename, ios::binary | ios::in);
if (!file.good())
    return 0;

// allocate buffer
data = static_cast<char*>(malloc(width * height * 4));

// read texture data
file.read(data, width * height * 4);

file.close();

int i;
for (i = 0; i < width * height * 4; ++i) {
    cout << static_cast<int>(data[i]) << "|";
}

// allocate a texture name
glGenTextures(1, &texture);

// select our current texture
glBindTexture(GL_TEXTURE_2D, texture);

// select modulate to mix texture with color for shading
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_DECAL);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_DECAL);

// when texture area is small, bilinear filter the closest mipmap
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_NEAREST);
// when texture area is large, bilinear filter the first mipmap
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

// texture should tile
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

// build our texture mipmaps
gluBuild2DMipmaps(GL_TEXTURE_2D, 4, width, height, GL_RGBA, GL_UNSIGNED_BYTE, data);

// free buffer
delete data;

return texture; }

Вот мой код использования:

Но если я правильно понимаю, половина из них должна быть нулями, а половина - 255. WTF или я что-то не так делаю?

Редакция: Пытался сделать это: 

data[0] = 0;
data[1] = 0;
data[2] = 0;
data[3] = 255;
data[4] = 0;
data[5] = 0;
data[6] = 0;
data[7] = 255;
data[8] = 0;
data[9] = 0;
data[10] = 0;
data[11] = 255;
data[12] = 0;
data[13] = 0;
data[14] = 0;
data[15] = 255;

И все текстуры черные (http://cl.ly/7KJd), изменили нули на 255, а texure - белые. Так что проблема в загрузке файлов!

В OpenGL белые текстуры отображаются, когда текстура неполная или содержит ошибку.

В большинстве случаев это связано с отсутствием мипмапов, но при использовании gluBuild2DMipmaps оно может быть не связано напрямую.

Вы должны попытаться позвонить glGetError, чтобы попытаться сузить вашу проблему: как упоминалось в комментариях, вы делаете много неправильных вызовов GL в опубликованном вами коде.
