Couldn’t find any solution yet.
Perhaps a codepen or fiddle? This says nothing.

The compiler is complaining about missing functions. Your shader is calling textureLod(...) somewhere, but that method doesn’t exist.
Maybe map or uv are abscent.
Code: textureLod(map,vUv,0.0);
What version of three.js are you using?
It’s “three”: 0.152.2
Do you mind demonstrating the issue with a fiddle? three.js dev template - module - JSFiddle - Code Playground
