I'm currently on a research project where we are making some trees for AR experiences and I'm having some issues with the PNGs I'm using for leaves. I model the trees in a program called Tree It and then export that into Maya to convert it to a GLB with Babylon.js' Maya Plugin.
Then to test how it looks I put the tree into Babylon viewer and it looks perfect. The png transparency works fine and there is no hazy white background around the planes i'm using as leaves.
Now comes the issue. When I drop the GLB into Reality Converter the pngs suddenly have a mostly transparent but still visible white background.
It seems the issue is with Reality Converter since I don't run into this problem anywhere else in the pipeline. I vaguely remember reading something about Apple adding a faint white background to pngs but I can't remember if i just imagined that.
Anyways here is a closeup of the issue:
