Texture problem?

OpenGL OpenGL: Advanced Coding
1

I have two textures in my scene. Half for sky and half for ground. When I ran displaying
these two textures in one code, they two
appeared. However, when I copy the same
code of displaying two textures in another
code. the ground one disappeared. I checked
that the texture for ground is loaded
correctly because I display it as sky and it
appears. What can be the problem? Thanks for
help.

When you say that your texture disappear, you mean that it is blank ?

Post your drawgl scene code pls

// texture1 is ground
// texture2 is sky
// I can see texture2 only
// if I switch them, I can see ground as sky.
// texture1 never appears. This piece od code
// works in another code. Thank you for your
// help

glDisable(GL_BLEND);
texture1->activate(); //texture is a class
