Rhino preview problem with baked geometry

Hello guys!

I made a definition in grasshopper and I created a brep. When I see the result in custom preview of grasshopper all seem to be fine. The problem is when I try to bake the geometry to a rhino solid opbject.

Does anyone have any idea what causes that problem?

Thanks in advance!

Post your definition with references internalized. Best guess just looking at this is that your surface normals are pointing in the wrong direction.

Thank you rasmus!

You didn’t internalize your referenced geometries in the definition :confused:
