The hinges and rails are certainly useful and a great addition to SH3D! At least if it were not for all the custom models that needs updating.

..extremely useful everytime the wind is changing...

[:)] As for a flagpole, well, I use it mostly to visualise wind, and not least shadows around a building. What is tricky, though, is to get the smooth proportions nicely textured and make the flag look fairly realistic. In real life, unless there is a gale, flags tend to flap helplessly around the flagpole - but then, maybe not as good for seeing wind. Anyway, here is the model with a more realistic flag, still hinged and texture mapped.
