Hi donmccurdy!
I’m having the same error:
“Uncaught TypeError: Cannot read property ‘extractUrlBase’ of undefined at GLTFLoader.load”
I recently downloaded the GLTFLoader.js and three.js from the the three.js site with its examples but I still get this error.
I posted my issue in a new post, could you please look at it!!
[Uncaught TypeError: Cannot read property 'extractUrlBase' of undefined at GLTFLoader.load]
Thanks!
