Hi!
The enable part is wrong; ypu must call pfOverride(..., 0) to allow
state changes
and you call pfOverride(..., 1) to freeze the states; so yor code must
be:
else {
TexMode = TRUE;
cout << "enable texture" << endl;
pfOverride(PFSTATE_ENTEXTURE | PFSTATE_TEXTURE | PFSTATE_ENTEXGEN, 0);
// not 1
pfEnable(PFEN_TEXTURE);
pfEnable(PFEN_TEXGEN);
pfOverride(PFSTATE_ENTEXTURE | PFSTATE_TEXTURE | PFSTATE_ENTEXGEN, 1);
// not 0
}
