For the purpose of animating intros and takes for business short films but also for blog graphic use, I wanted to animate a flag. The underlying Blender project file allows to use different flags (this uses Turkey as an example, as I used it for an image on a blog). Also, with a material node setup of multiple textures, the flag could be exchanged during animation.
The background (credits/copyright to falconi on skyscraper forum) is a simple image added within the compositing with an alpha-over node, as the flag is animated with transparent background. I tried to add a slight blur behind the flag to ensure it does not look artificial on top of the background. Overall, the test needs more compositing.
If you would like a tutorial on how to build things like this, let me know. Also, make sure to check out the inspiration tut I used to create this from gr8effect on youtube (look for his channel and the cloth tutorial).
