Hi,
I have made a spherical shape on rhino but in rendered view, there is a line on my sphere which I can’t seem to remove. I have tried ungrouping/exploding but the latter states that I cannot explode single surfaces.
I have attached a screenshot of what the model looks like in rendered view.
Hello - that is the seam on the sphere - in the display mode settings (Display tab) disable/un-check the display of tangent seams.
Hmm - Rhino 5… not sure that setting was there way back then… I do not have 5 here.

Hi, rhino 5 does not seem to have this setting 
but thank you for the advice!!
