Smooth edges are sharp after rendering I'm a complete beginner at blender so please help in a way a beginner can understand. I'm following the blender guru's blender beginner tutorial on youtube and im on the final 9th episode. I've made a donut and before I put it through a final render, the frosting is nice and smooth. But after I render it, the drips of frosting are sharp and triangular. I have NO CLUE what I did or how to fix it. It makes zero sense and I could really use some help. Heres before final rendering and after final rendering.
Make sure your render settings for your subsurf modifier are at least the same or higher than your view settings. In the following image you can see view subdiv is lower than render. 



Set your render subdivs higher or equal to your subdivs.
