Conversion error (after >1 hour of converting)

[mflux]

Here is what I'm trying to convert: https://dl.dropboxusercontent.com/u/705999/Paris.zip

Command I ran
node node_modules/obj2gltf/bin/obj2gltf.js "Paris2010_0.obj" model.gltf -s

After seemingly stuck converting, I decided to let it run for the rest of the day. After about 1.5 hours or so, a js error finally came up:

Any ideas on what could be going wrong? It's not that big of an obj (around 40 mb with 30 mb of textures).

Something seems to be breaking in the optimizeForVertexCache stage of gltf-pipeline, which obj2gltf uses.

Whether or not there's an easy fix for that, we plan on adding an option to not optimize the gltf. This will significantly speed up conversion times. For something like this it should be less than a minute with that option.

[lilleyse]

Partially fixed in #49 since gltf-pipeline is now off by default and it will not break at this stage.

A separate issue with this file is some faces have more than 4 vertices. There's a new issue open for that: #55
