Display Mode Tecnical doesn't work? (solved!)

So I have to make a technical display mode out of this shape, I selected ‘Technical’ in displaymode, but it doesn’t work and I can’t find a solution? Can someone help me please?
I made the shape with grasshopper

The Grasshopper preview won’t use the regular Rhino display modes unless you bake the geometry first. Grasshopper has custom shader components for display but nothing like technical mode is possible to my knowledge.

Correct, it isn’t.

Will it be possible one day?

Possible, sure. We haven’t really talked about this in house much yet, but the preview code is going to be rewritten so anything is possible. Whether or not it will happen depends on how much work it would take, and I have no idea yet.
