Unreal Animation and Rigging Toolkit Proxy Geometry came out transparent

So, my ART proxy geometry kept coming out partially transparent. Anyone know how to fix this?

I tried reinstalling ART, deleting entire plugin folder, but making a new proxy mesh from scratch with everything at default still produces something like this.

I’m using UE4.16 with UE 4.17 also installed in Maya 2016 Ext2 SP2 on Windows 10 x64
