I have never actually used external files(my displacement images) in jsfiddle sorry, however, it is basically this exact simple example but using my own DisplacentMap image file and Texture image file for the color. [three.js dev template - module - JSFiddle - Code Playground](https://jsfiddle.net/2jphv7oc/)

i included the .png here if youre interested…  
(is NoData vs ‘Transparent’ an issue?)

it also has lots of similar questions/answers here: (alpha map as you suggested)

> My bad. Here is the PNG. I uploaded it to pinterest. [[image] ](https://i.pinimg.com/originals/52/2a/65/522a658dd845380b3bac3a2a32a4b014.png) Why it’s a link instead of uploading here: For some reason, when I try to upload here, it’s converted to JPEG. The image was generated with the free drawing software, Krita, so I wonder if there is some data exported with it that makes this forum want to change its type:
