I'm new to Blender fluid simulation and want to fill a cylinder with water.
As you can see in the following image, it fills up the cylinder, but on the rendering result, there are strange black stripes.
I tried to increase the fluid resolution to 300, but it didn't resolve this issue.
The skyblue background is composed of 3 planes. I thought open space in other three axis could be a cause, so I put that cylinder in a cube, so that it resides in a closed area.
Unfortunately, it didn't solve the problem neither.
Does anyone have an idea what causes this problem? I would really appreciate your help.
