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.
