3-Layer Marshmallow using Cycles

[NodeNabob]

Hello.

Still fascinated with using Cycles to do realistic food materials.

After a LOT of experimentation, I came up with a three-layered approach to doing realistic marshmallow material. Here is the final result:

Rather than rely on the Subsurface Scatter node in Cycles, I decided (after much experimentation) to use a multi-layered approach, similar to nested Russian dolls. Each layer was formed by copying and scaling the original cylindrical mesh. The layers are as follows:

-Marshmallow Core
-Marshmallow Mantle
-Marshmallow Crust

Subsequent posts will show the node layout of each.

Hello, again.

Here are the three layers to my Marshmallow material.

The Marshmallow Core node layout:

The Marshmallow Mantle node layout:

And finally, the outermost shell has the Marshmallow Crust node layout below:

I can go in a bit more depth about the exact colours used in a future post. I’ve reached my three pic limit for this post.

Here is more detail about the Marshmallow Core material:

Both of the Toon shader nodes have the same colour, which is not merely pure white. The RGBA for their colour is:
-R: 1.00
-G: 1.00
-B: 1.00
-A: 0.02

This produces a transparent effect which works in concert with the other two materials.

My next post will have details about the Marshmallow Mantle.

Details about the Marshmallow Mantle material:

The top Diffuse node has the same colour as was used in the Core:
-R: 1.00
-G: 1.00
-B: 1.00
-A: 0.02

The bottom Diffuse node has a full-alpha grey, to accentuate the webby parts of the Voronoi texture:
-R: 0.70
-G: 0.70
-B: 0.70
-A: 1.00

My final post will have details on the Marsmallow Crust.

And finally the details of the Marshmallow Crust material:

The colour used in the Translucent node is the same translucent white which appears in the two layers underneath the crust:

-R: 1.00
-G: 1.00
-B: 1.00
-A: 0.02

Thanks for reading! I will return with more materials as soon as I’ve had more time to experiment.

Hello, again.

Tried the three-layer approach to the well-known Suzanne mesh:

And to a Cube mesh:

I can furnish the layering and mesh details if requested.

Where’s the chocolate, the graham crackers, some sticks, and a crackling fire? Interesting material.

Hmmm… Interesting, though in all honesty I’m not entirely sure this complex of setup is required. However I too have tried for many hours to replicate the familiar marshmallow material, and have not reached a satisfactory result. Maybe in more complex scenes this shader will indeed prove more efficient than others Thanks for sharing.

what kind or how do you make the maps for this
why not make 2 models one with UV and one with proc texture only!

would you mind sharing a sample file for this
would save a lot of time for a lot of people

and nice tut and sharing it

happy cl

Hello. Just back from a long road trip last week. I see that there’s interest in the .blend file.

Let’s see if I in fact have 10 posts and can post this pasteall link:

I can definitely do a video tutorial but this may have to wait until mid-September.

Hello, again.

Here is Part I of a video walk-through of the layers in my marshmallow set-up. Parts II and III will be posted soon.

Hello once again. It’s been well over a month, but here is the second short video showing how the Mantle material is set up:

The third and final video in the series will show how the Crust material was set up. Thanks for watching.

I just discovered the Blender Material Preview Scene (BMPS), which has been modified to work with Cycles. It can be downloaded at:

Download: Cycles Material Test Scene

Here is the 3-Layer Marshmallow Material shown in BMPS. Comments are welcome.
