I have this blend file that seems to be growing.
The file size is now about 250MB. It contains this scene and the texture of the flag is 265kb and the texture of the sky is 640KB.
I have a wind blowing and I intend to render this scene as an animation. I have played the animation a couple of times and I have the feeling that this causes the growth of the file. What could be the reason for the ridiculous file size ?
