OpenGL: using FTGL and textures

When using FTGL texture fonts, everything works perfectly until I use another texture somewhere else in my program. Then the original texture of the font seems to be lost, and as a consequence, the characters are drawn as black dots. After playing with the various parameters of glTexEnvf, I think the problem is simply that the font doesn't load its default texture back when writing.

Is there a way to access this default texture and bind it before writing?

Try surrounding your calls to rendering the font with

  glPushAttrib(GL_ALL_ATTRIB_BITS);

and

  glPopAttrib();

(as rotoglup suggests.)

I've never used FTGL but you could simply be having problems with the active texture unit.

Did you try using a texture unit other than 0 for your own textures and leaving GL_TEXTURE0 to FTGL ?

The relevant documentation is here if you need it.
