Right now my human model looks way too smooth, in cycles render. I prefer the bumpier look of Blender render, but I want to use cycles. How can I create a bumpier, lumpier-looking human, something that looks more lifelike? Specifically, I want my good-natured wise man character to have a lumpy belly that ripples when he laughs! I am currently using diffuse BSDF node and a little bit of glossy BSDF node. Thank you for help!

Edit: In response to atomicbezierslinger: I wanted to go ahead and say that yes, I do mean a protruding round belly, with slight rippling and dimpling, just enough to look like lifelike. This is the closest I've come to finding a photo reference, I hope this is not an inappropriate photo. See here how the belly is slightly dimpled and lumpy.

Just slight dimpling and lumpiness. I will see if i can find a better reference photo.

Since you mentioned it, I would also like to know how to create fat folds that move realistically; that would come in handy for another character. I appreciate all help and I will look into the SSS Shader.

  • $\begingroup$ Please place an image in your writing above to make it easier for others to help. By lumpy do you mean a protruding round belly, ..... or folds of fat, or many protrusions such as in 1 inch size protrusions on a 5 foot human. Or something else? $\endgroup$ Commented Sep 9, 2015 at 6:23

  • $\begingroup$ It is unfortunate yet no wisemanbellyripple modifier available in 2.75a only available if plug-ons. but also hard even so still. If your human wanting lifelike, best of things you had better do is studying actual jolly-mans lifelike bellyripple. How many hours you spent watching really belly ripple? I bet nothing! You post an question showing not anything research! how you are gonna use a stacksexchange not even have some sense to study a bellyriple first beforehand ; and various individual having to instruct you "use an sssshader" because you doesnt know even that!! what's?!! $\endgroup$

  • $\begingroup$ To Mentalist: I have spent many hours examining my own rippling belly, but this does not reveal the secrets of the elusive Blender. I have far to go. $\endgroup$

  • $\begingroup$ @WishyQ, creating realistic skin or anything realistic for that matter is a pretty hard task. It involves many layers of work on modeling, shading, texturing, lighting, rendering and post production. I doubt you'll be able to get a thorough answer to your question here (unless someone makes you a several hour long video tutorial or 50 page long answer). I'd suggest you look for tutorials and courses for realistic human sculpting, texturing, shading and rendering. I'd start with cgcookie.com/courses $\endgroup$

Since it seems you found it useful, I am re-posting my comment as an answer:

For the dimpling use a combination of a Displace Modifier and some bump in your material. For the skin material add an SSS Shader to your glossy+diffuse mix. A skin texture image into the Diffuse color input would help too. For the ripple you can use a Cloth sim like in this tutorial. or a Soft Body sim like in this tutorial. Finally here is a Soft Body tutorial specifically for belly ripple, lol - although it is in Spanish. Good luck!
