Blender 2.83 - Hair particles with big diameter showing cuts in strands I am trying to make an anemone like model and want to render the tentacles as hair particles. So I need to increase the root diameter quite a lot. It is actually a few meters now (which of course is not realistic), but I don't think that adds to the problem.
In the render preview you can see cuts in some hair strands and I wonder why this happens.

For the shader I do not use Hair BDSF but a simple custom one for now. I tried to adjust render steps, segments, render path settings, shader .. but nothing has an effect on the issue. I'll append the file to fiddle with.
If you increase the render steps (Render Tab -&gt; Path) to 5 and check the B-Spline option the result gets smoother, but then the strand will look like an elephant's trunk (more cuts) :-) like so:

The interpolations just does not seem smooth. I forgot to check &quot;Close Tips&quot; for the screenshots, but this also does not have an effect on these cuts.
I could always make a few tentacle objects and use a particle group instead, but I wonder if is not possible to solve this using the standard hair system.
Happy if you have an idea.
See if this works for you, it seems to have fixed the issue in my machine.

Change the Primitive to curve segments in Render Properties &gt; Hair.
