How do you make cotton balls fluffy with perhaps some loose bits hanging. enter image description here

  • $\begingroup$ It's a good question. Could you tell a bit more about the context? What is it for? How is it going to be rendered? What distance is it going to be viewed from? $\endgroup$ Jun 29, 2019 at 17:10
  • $\begingroup$ Firstly, it is not for myself, but for someone in Facebook. When others give answers, I will show this page to a guy. Besides, I thought cotton balls are challenging to create and thereby interesting. So, I have got screenshots of nodes for cotton balls and paste them into my scrapbook as in link here. Credits on screenshots are given. Links to sources are included. docs.google.com/presentation/d/… $\endgroup$ Jun 29, 2019 at 17:21

    $\begingroup$ Besides, I am really interested in cotton wool, especially for future usages. $\endgroup$ Jun 29, 2019 at 17:37

I've tried this, I think it needs more hair work though, to get the fluffy thing. For the material, I've used a Noise Texture that I've scaled on one axis to get the stria effect. Emission is here to give a bit of luminosity and softness to the object, too much shadow would make it look solid like a stone, it somehow simulates a transparent effect. And at the end a bit of Transparency, with a Fresnel as factor, to make the contour a bit evanescent. The hairs are actually long extruded rectangles with a material that also use a mix of Diffuse, Emission and Transparency.

    $\begingroup$ Can you explain what the nodes are doing? Why emission? Is this on top of hair particles? $\endgroup$

  • $\begingroup$ I forgot to thank you long time ago. Sorry about my lateness. I am back to this thread. I must remember to put this node tree in my scrapbook. Thank you very much. $\endgroup$ Dec 1, 2019 at 17:55
  • $\begingroup$ You're welcome, I hoped someone would find a better solution but it doesn't look too bad ;) $\endgroup$
