Hello! I am using ar.js in combination with three.js (r136).  
Im trying to load a custom 3d model from blender (model doesn’t have ngons, I tried both OBJ and GLTF loaders) but when I try to view it there were some flashy polygons. I thought that it was z-fighting so I enabled logarithmicDepthBuffer. After that there are no flashy polygons but model isn’t correctly displayed ([Image — Postimages](https://postlmg.cc/94q98Z9r)). I tried to view my model in web viewer like [https://3dviewer.net](https://3dviewer.net) but there it is displayed correctly. Can some one help me?  
I attatched all my files and made a public online demo ([LoadingR](http://purpleflowers.ml/arerror/))
