This flag is the result of having spent 4 hours trying to get a flag into my project that actually moves reasonably using the cloth Unity feature. The asset is based on a free to use flag model and uses the cloth animation from unity 5.4 but it also tested ithout issues to 5.3.4.
The object to use in the package is called flag_med and is a prefab. The flag is just under 4m high and has a 1000 kg 1x1x0.2 meter base. The flag itself has only 45 points so overhead is kept to a minimum
Also included is the source fbx file. Feedback welcome, but please remember that this is just for saving your time.
