Greasepencil to Sketchfab - Pagoda of the crystal relic

Decided to revisit working with grease pencil and tried to find a way to upload it on sketchfab.
heres a video of the greasepencil version and the version i got working in sketchfab

Heres the model up at sketchfab

the process I followed involved 3 steps

  1. converting the greasepencil object to a path
    001 path
  2. adding some thickness…
  3. Converting this to mesh
    003 mesh
    if the mesh is too dense(most likely) use the Decimate modifier to optimize it

This gives you all the paths converted to usable thick meshes… which works in sketchfab.
Now I need to figure out how to get fills and brush styles(if even possible).
