I use the technique of nehe to make a mask,
glBlendFunc(GL_DST_COLOR,GL_ZERO);
glBindTexture(GL_TEXTURE_2D, this->poTexture->GetIDMask());//Select Our Font Texture
glCallList(this->List);
glBlendFunc(GL_ONE, GL_ONE);
glBindTexture(GL_TEXTURE_2D, this->poTexture->GetID()); //Select Our Font Texture
glCallList(this->List);
and I seek has to make the same thing by using the multitexturing, somebody has an idea?
Thank
