I have the same issue. My script generates a custom PDF with 3D preview of the model and with annotations. I can’t really understand what’s going on, but I have noticed following:

  • Grasshopper shows the geometry when I select “Custom Preview” component in Grasshopper (the same preview as if I select any GH component with preview on)
  • Custom Preview sometimes works fine when I change the material or the colour (on Custom Preview input)
  • This bug first appeared in a GH file saved on 30th May where I added Model Object components and also Content Cache
  • File saved on 20th May works fine (Rhino version is the same in both cases)
