Hi,I was wondering if you could help me with the render of my tornado : (link of the tutorial : http://cgcookie.com/blender/2012/05/04/creating-a-tornado-in-blender-with-particles-and-the-smoke-simulator-part-02/ )I would like to get rid of the black points in the middle of the tornado, I have tried with : - integration to 0.2, and high res division to 2 (first image)or - with integration to 0.05, and high res division to 3 (second image)
(high res : 3, integration 0.05 ) :

Any idea?Thank you very much
