Hello @nathanletwory ,
Thank you for your reply.
Yes, the vertex color material works when a Grasshopper-Ladybug simulation is baked in Rhino.
The Arctic mode works if to the mesh is applied a a different display mode with “SetObjectDisplayMode”.
If the geometry is not baked, but previewed in Grasshopper, the Arctic and Raytraced modes don´t show mesh colors. It is not crucial now that I know “vertex colors” option. It would be just a bit more flexible if that would work without baking, with the GH preview in Rhino.
Yes, this is it. Here is an older post with a workaround, but it slows down everything or can create a bottleneck for large simulations if used:
The color information of meshes is related to the values assigned. It works well with a Heatmap in Ladybug.
I don´t remember accurately but I have tried it 3-4 months ago with Rhino.Inside to preview the GH, or the baked Rhino mesh into Revit, but it was not showing the colors of the mesh.
I have tried Rhino with Semantic plugin of Proving Ground that can preview Rhino models in Power BI. Their workflows worked when the mesh is exploded to single meshes with values and reassigned in Power BI. Doing it this way creates a huge bottleneck and works only well with a limited amount of meshes.
Thank you again for your time and help @wim and @nathanletwory
