openGL/Pyglet texture graphics vanish when drawing sprites

Question

My code draws a 3D world, with a 2D set of graphics on top of it. The 3D world is made out of textured quads and the textures are generated with the following code:

textures = []

image = pyglet.image.load(os.path.join(img_dir, "magic.png"))

textures.append(image.get_texture())

glEnable(textures[-1].target)
glBindTexture(textures[-1].target, textures[-1].id)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, image.width, image.height,
    0, GL_RGBA, GL_UNSIGNED_BYTE,
    image.get_image_data().get_data('RGBA',
    image.width * 4))

The quads are then drawn with (the other 2 just have different coords):

glBindTexture(texture.target, texture.id)
glBegin(GL_QUADS)
glTexCoord2f(0.0, 0.0); glVertex3f(4.0, -2.0, 100.0+self.clock)
glTexCoord2f(1.0, 0.0); glVertex3f(4.0, -2.0, -100.0+self.clock)
glTexCoord2f(1.0, 1.0); glVertex3f(-4.0,  -2.0, -100.0+self.clock)
glTexCoord2f(0.0, 1.0); glVertex3f(-4.0,  -2.0, 100.0+self.clock)
glEnd()

I have set up the correct parameters when drawing the 3D and 2D graphics, and when I draw a 2D triangle on top of the 3D quad (with the following code) everything works fine:

glBegin(GL_TRIANGLES)
glVertex3f(0.0, 10, 0.0)
glVertex3f(-10, -10, 0)
glVertex3f(10, -10, 0)
glEnd()

However, I then try to draw a sprite and the 3D quads lose their texture and are drawn as white.

self.spr=pyglet.sprite.Sprite(pyglet.image.load(os.path.join(img_dir, "largebullet.png")).get_texture())
...
self.spr.draw()

Note that there's some fog in the background

Answer 1

I found a solution to this, by running glDisable(texture.target) on the enabled textures after they were drawn. It's not ideal because they have to be reenabled again, but for now it works ok.

Answer 2

I ran into a similar problem to this, and I found that the pyglet Sprite class tends to disable everything in the OpenGL state that it sets. You must reset a lot of things each time any sprite is drawn.
