I've got a scene with paper sheets moving along paths (with a modifier). But there is something weird : while everything looks fine on the viewport, it seems that there is a lack of geometry when rendering (we can see kind of horizontal lines on the paper).

enter image description here

I checked : I have soft shading enabled on the meshes, I have a subdivision modifier enabled (on render too), and I also checked the resolution of the curves (12 on preview, 0 on render)

So why this ?

Thanks !

  • $\begingroup$ Check that the number of subdivisions is equal or higher than the ones for the viewport. $\endgroup$ – Robert Gützkow Sep 5 '19 at 15:32
  • $\begingroup$ already checked, it's not that... $\endgroup$ – gordie Sep 5 '19 at 15:36
  • $\begingroup$ Have you not answered your own question? if you have geometry with curves and you have the render view to 0? it wont be shown, but 12 in the viewport - try making both 12 and see if it solves the problem. $\endgroup$ – Facity Sep 5 '19 at 15:57
  • $\begingroup$ @Facity : 0 = use of previous resolution (12 in this case) $\endgroup$ – gordie Sep 5 '19 at 16:45
  • $\begingroup$ Can you add a screenshot of your modifier settings? $\endgroup$ – Robert Gützkow Sep 5 '19 at 17:07

Seems that this is happening because I use 'Simple' subsurf, not 'Catmull-Clark' !

Anyway, seems there is a bug since it doesn't look the same in the viewport... ?
