Adding a large .glb DataBase

Hey there, im using cesium ion for converting my .glb database created in blender (with blendergis), exported as .glb and then converted as a 3d scan… the problem is the following:

  1. models go upload untextured (although in the .glb previewer they seem with textures)
  2. very large database with high polygon count seems to get stuck at 14% tiling and then not move.
    I would really appreciate some assistance =)
