Can you provide a sample file that shows the problem? It doesn’t need to be a full model. I suspect by “a grasshopper definition” versus an “HB model” you are referring to using faces and meshes as the input.
If that’s the case, try converting all the geometries to a joined mesh, translating it to a shade object, and then creating an HB model that only consists of shades.
Yes that’s exactly what I meant. Thank you I will convert it to shade objects. I am sharing a link for my base case, however, I will try converting it to a shade object, and if there is still a problem, I will let you know. Thank you. Mona - Case Study.gh - Google Drive
