Este es un seguimiento de unPregunta anterior.
Suponiendo la siguiente configuración:
\documentclass[margin=10pt]{standalone}
\usepackage[dvipsnames,svgnames]{xcolor}
\usepackage{tikz}
\usetikzlibrary{mindmap,shadows}
\usepackage{fontspec}
\tikzset{golden/.style={
fill=none,draw,
path picture={\node[every node/.style={}] at (path picture bounding box.center)
{\includegraphics[width=#1,height=#1]{GoldLeaf.jpg}};},%},
},golden/.default=4cm
}
\begin{document}
\begin{tikzpicture}[mindmap,
font=\large\bfseries\sffamily,
grow cyclic,
every node/.style={concept, circular drop shadow,
%minimum size=0pt,
execute at begin node=\hskip0pt},
%concept color=magenta!70!black,
root concept/.append style={
font=\huge\sffamily\bfseries,text width=8cm,concept color=Gold,
golden=8cm},
level 1/.append style={sibling angle=360/10,
font=%\color{Seashell}
\bfseries\sffamily
\LARGE,
level distance=35em,
inner sep=0pt,
text width=4cm,
sibling distance=1cm,
concept color=Goldenrod,nodes={golden=4cm}
}]
\node [root concept] {Root Concept}

child {node {Node}}

child {node {Node}}
child {node {Node}}

child {node {Node}};
\end{tikzpicture}
\end{document}
Lo que genera el siguiente resultado:
El gato del usuario Schrödinger sugirió "un enfoque diferente utilizando path fading". ¿Cómo puedo utilizar un desvanecimiento de ruta para aquellos conectores con una imagen (de fondo)?
Respuesta1
Esto agrega un estilo que utiliza un gráfico para las barras de conexión. El uso es
use image for connecting bar=<graphics>
Tenga en cuenta que esto requiere que establezca el color del concepto para los niños,
every child/.style={concept color=<color>},
donde el color se usa para el halo.

En realidad, esto se ve mejor de lo que pensé.
Esta es una versión que tiene una imagen de fondo general. Cosas como las sombras no funcionan como de costumbre. La sintaxis es
\begin{Mindmap}[<options>]{<graphics>}
<mindmap code>
\end{Mindmap}
y aquí hay un ejemplo:
