Hi @Aaron_Jeewood I reproduced the long wait when the diamonds were displayed, thanks for that detail. I didn’t wait more than 5 mins before quitting Rhino so I don’t know how long it would take but I figured out the fix regardless. The issue appears to be two fold, the number of polygons of all of the combined diamonds and the NURBS objects passing their render meshes to Brazil which takes time. Luckily they are block instances so the fix is easy.
- Double click one of the diamonds to open the block editor
- Use ExtractRenderMesh on the diamond
- Delete the polysurface diamond
- Select the mesh diamond
- Use ReduceMesh on it and check the Planar Only option
- Accept the block edit changes
It should render then. Before these steps you could see that the render mesh for one diamond is 318 polygons and there are 3,773 diamonds so it was roughly 1.2 million polys just for the diamonds. More polys = more time when it comes to rendering. We cut it in half with this workflow while also cutting out the middle man of having the NURBS objects pass their render meshes to Brazil.
Did that work for you?
