Thanks for that - Ive put my entire project here https://bitbucket.org/skyyguy1999/deadends/src/master/ I’ve copied the fiddle verbatim, the only thing that is different (because I am in node) is writing THREE.ShaderPass or THREE.Effectcomposer instead of just new EffectComposer. Is this a problem?
(to run it follow the directions - cd into directory and npm install, npm run start)
