Hello I'am new to blender, and I'am creating a ink drop in water animation using quick smoke simulation cycles render then after I finished rendering there's a strange black parts in the animation.
I would like to ask how can I remove these parts.
The attached link is the animation I rendered and the blend file. https://www.dropbox.com/sh/unismmxg1w31y3v/AAD24U5jXFh5umXuNgczPao8a?dl=0
