Hello everyone 
I[m trying to bake a mesh, but the result is weird. Some surfaces are showing off as lines only. Does anyone know why, or how to solve it? in the preview from grasshopper they´re all fine.
Thank you
From Rhino, select the mesh and run UnifyMeshNormals. If that does not help, then please post your mesh.

It worked! Thank you so much! 
Great - you can do this before you bake using this:
