The scene is animated, the tornado is moving and twisting, please see the previews below. One is the final rendered result, the other is preview of the particle movement.
1. The rendered streaming file has lost some of its quality dew to the video compression. The original looks like the preview images.
2. VERY IMPORTANT! Non Lightwave users, as far as I know there is NO WAY to convert this scene to other software. This scene works ONLY in Lightwave.
For similar objects, or slightly changed, or custom modeling contact me.
