Hey, I don’t know what I did, but I managed to figure this out by accident in Redshift. I had the same issue happening to me. What I did to fix it was I went to the Redshift Volume Material > Scatter, and on the Gradient, I selected the Black Knot and set the Knot position to 0.4. When I did that, Redshift was clipping the unnecessary fluid.
So I’m guessing…that I’m telling Redshift to clip values near 0.4…correct? Since Black is 0, thus transparent, White is Opaque equals 1. Bringing the Black knot closer to the White Knot on the Gradient clips out the density, and by how much depends on how much you move the black knot. This case its .4. However, if I fiddle with the Advanced Settings, I found that I had to fiddle with the knot again just a tiny bit more.
Since we’re dealing with 0 & 1, 0 being Black and White being 1
I used .4 because anymore, and the
