Hi Peter,
Beaware, layering Shaders and layering Textures
are two different things.
Where layering Shaders is just like (in the real world)
putting a second layer of paint coating on a surface.
Where the "outer" coating is transparent, you can see the "inner"
one. This is more time consuming on the render process and only
makes sense if you need to have different MATERIAL characteristics
like shininess or specular rolloff on one surface.
Example: "inner" Shader is a dull Lambert and on "top" of it
is a (partially transparent) Blinn Shader.
What you're probalbly after is putting different Textures on one MATERIAL.
As far as I know there are at least 4 basic different ways to do
that:
-Layered TEXTURE
-Stencil Texture
-and of course as mentioned by Aleks advanced methods like using the
BlendNode....
and (as far as I know the most economic way, please someone correct me:)
-feeding a different texture into the DEFAULT Color of an existing Texture.
(For this to make sense, you will turn of Wrap UV in the Placement Node,
and make sure the Texture covers only parts of the surface. If you feed
a second texture into its Default Color, it will show up "underneath" or
"next" to the first one. Now if you want more, just feed into the "New"
DefaultColor
your next Texture and so on...)
This used to be explained in the Version 4 Docs, not sure about nowadays
docs....
Hope this helped a little too.
regards
Karsten

> Thank you for your advice, Simon and Aleksander. The creation of layered
textures is still very confusing. I am working my way through it. I can
easily create two shaders, apply 2d photos to them and MMB them into the
layered shader panel. I have not been able to figure out how to blend the
two shaders so that you can see both, and then apply that to an object. And
then, how would you connect a third..fourth, etc?
