I’ve had this problem a few times.
Never sure what’s going on.
Usually I’m running a kangaroo bouncy solver twisting a mesh net and using a loop component to update how the forces affect the net .
I get so far everything clean then all of a sudden it spoils
The grasshopper definition won’t display properly in rhino
Geometry disapears, some text rendered to screen is till there and updating, the model is still running in grasshopper, but unless it’s selected in the canvas … no geometry or custom preview geometry will display.
The rhino viewports then also start bugging out. Some of them skip to other views. If I zoom on them Sometimes they go kinda blue then blank - grey
resetting to the standard 4 viewports doesn’t help
Shut down rhino and reopen + reopen gh and it all comes back but very soon disappears again.
Having upgraded to Rhino 7 I hoped this problem would have disapeared
