I had high hopes for the Hops component, but my experience working with them is full of problems. It’s not easy to track what is wrong each time, exaple below shows that only 1 out of 3 hops components that point to the same GH definition actually works. They should allow tree access, but sometimes they only work with lists, or don’t work at all. Even when Hops component finally works, if I close and reopen GH definition they are stuck at “solving” and I need to disable & enable Hops component for making it to work again.
I work with Rhino.Inside.Revit and I have thousands of objects to be ShrinkWrapped so I thought Hops would be perfect to solve it Asynchronously and do not lock my UI.
This doesn’t touch the topic of starting the compute.geometry and making Hops component generate themselves.

Some random problem with the Shrinkwrap component inside
Hops definition is as simple as it can be…
Three Hops components pointing to the same GH definition, yet only one managed to output geometry
What are they solving? I need to re-enable them after the GH file reopen
WISH: Component placeholders instead of disappearing Hops components when compute.geometry isn’t working.
