3D viewer for ply, stl, obj,ย Lwo,ย glb, cob,ย scn, c4d,ย etcย (binary & ASCII) with conversion & thumbnails would be helpful.ย ย Maybe use something of Sourceforge etc to make it quickly! Or from Blender or BforArtistists.
Sounds like a nice idea to complete the Viewer capabilities of FileVoyager.
Not on my priority list as I have higher priorities, but added in my whishlist.
