Black lines in Smoke render 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.

Thank you in advance
Try 2.80 version (or 2.79 daily build) there is no this behavior:



And by the way, try this setting in color ramp, in my opinion, it produce more cooler ink-drop look.

Maybe this is a bug, and it was fixed in new version...

in 2.79b adding a little bit tint of color also helps:
