@silentheart00 When I tried to import the Blender 2.8 file in Sketchfab it gave an error when interpreting the file. I then tried the only two exporters available in blender 2.8; Collada (*.dae) and Alembic (*.abc).
The first one did import, but only a part of the model was visible. When I activated wireframe I saw only the edges where there but more than half of the faces where gone.
When I imported the Alembic file, it worked, but some of the faces where glitching out a lot. I later found out that some of the objects (the tops of the middle and the right part of the house) in my scene had errors in them (not visible). When I replaced them with new objects it worked a lot better. Then I still had to edit the parts I used the bools on so they only contained quads. Then the model displayed correctly.
I canceled the bool modifiers in the walls behind the plates with the holes to keep the mesh simpler, else I had to remodel a lot of stuff in edit mode to let the model be watchable in Sketchfab.
Earlier on I had some crashes when turning on the Eevee rendered view ( because earlier I used OpenGL mode). I suspect the errors in the data where generated arround that time, or maybe where the cause of the crashes.
