This question might be stupid, because others seem to get the code to work, but I wonder which map shall be loaded. Should I create it on my own, is it an example-map from an older GS-version (I have GS8) or have you uploaded it and I don't know it?

And does it also work without mtlFX.h? I don't have it so I commented that header out and it works (apart from the map-problem).

But though I don't get it work yet, it helped me a lot; thank you.
