When I try to add 3D Font to my program it screws up everything. It appears that it flips all my normals or starts rendering all the triangles in the opposite direction. How can I fix this? This code seems to be the problem: .... .... glListBase(nFontList); glCallLists(6,GL_UNSIGNED_BYTE,"MY TEXT"); ... ...

Why are you passing a string to the lists parameter of glCallLists?

From MSDN:
const GLvoid *lists
The address of an array of name offsets in the display list. The pointer type is void because the offsets can be bytes, shorts, ints, or floats, depending on the value of type.

Because that is the type of the third parameter in the definition of glCallLists()

I don't think that the line you looked at is the problem.

glListBase(mylist);
glCallLists(strlen(mytext), GL_UNSIGNED_BYTE, mytext);

In my 3d font class, after being setup, does the same as yours.
The first parameter is the length of the text, the second what type it is, the third which ones it'll pick from the list. What I did notice is that you set the first parameter to 6, but the string "MY TEXT" has seven characters, space counts as a character. Check that and if it doesn't work, let me know.

That length isn't the problem. But those lines of code, or something about them is because if I comment them out everything works normally.

You did the code in Visual C++?? If so send me the source and I will look at it. From what you say, it should work.
