Very rough and dirty test on collisions. I need to get the smoke to hug the skull closer, improve the quality and set a scene with some more interesting layout, lighting and animation up hence the reflection flickering on the skull and the naff floor as they are just a placeholders for the TurbulenceFD testing. When it is all done I will put up a tutorial and scene file.
